Topo Athletic Ultrafly 2 Review Facts
Watch Video Review

The original Topo Athletic Ultrafly resulted in a decent amount of success but the company updated the sneaker and made the most recent version more cushioned and supportive. The sneaker is surprisingly durable considering the fact that it is relatively lightweight, thanks to its carbon rubber outsole and layered ultra-lightweight mesh upper. This version of the shoe features a lower drop than its predecessor but still delivers an excellent amount of cushion. One shining feature that is evident in this shoe, as well as all of Topo’s running shoes, is the anatomical shape of the sneaker which allows for your feet to spread naturally. This will help you feel more comfortable and less constricted as you run. The subtle style of this durable running sneaker does not do justice to the great performance that it delivers.

Editor's Pros & Cons

  • Extremely durable overall design
Cons
  • Some say the upper is too stiff 
  • The wider toe box may be too wide for those with narrow feet
Outsole
Outsole

Outsole

The updates to this sneaker do not really extend to the outsole because it is virtually unchanged from its predecessor, the Topo Athletic Ultrafly. The design of the outsole is meant to be naturally foot-shaped to allow for a comfortable and efficient running cycle. The outsole is made up of an extremely durable carbon rubber material which covers most of the forefoot and then follows the sneakers’ outline around the sole. There are flex grooves featured in the forefoot area which will help the sneaker to deliver a natural flexible experience on toe off. There is no aggressive lug system but there are a number of different shaped lugs interspersed with grooves in the rubber which will allow you to grip the ground and move over uneven terrain.
Midsole
Midsole

Midsole

The midsole of this Top Athletic Ultrafly 2 features a 3 layer EVA foam system making it Topo’s most cushioned road shoe to date. The three densities of the midsole deliver great cushioning at any distance. The top portion of the midsole is the softest, followed by a responsive and springy middle layer, ending with the most firm of the three layers toward the bottom which is evident by the pop of color. This firm cushioning material will provide stability and guidance to your foot because it is placed on the lateral and medial sides of the sneaker. The midsole also includes a removable Ortholite insert for added cushioning and comfort as you run. Ortholite is designed to wick away moisture and prevent the growth of bacteria that tends to cause bad odors.
Upper
Upper

Upper

One thing that Topo always does well in their running shoes is the wider toe box, rather than the traditional tapered toe box. This allows your foot to spread more naturally and eliminates compression and discomfort of your forefoot. This sneaker also features great lockdown in the heel which will help prevent your foot from slipping out of the shoe. This updated upper is made of ultra-lightweight mesh material that allows for excellent airflow. The printed overlays that are placed on the midfoot of the shoe help the sneaker to hug your foot securely. Many reviewers have commented on how well the sneaker fits around the midfoot, making their run very comfortable and supported. The upper material of the Topo Athletic Ultryfly 2 is a little heftier than other sneakers featuring a mesh upper. This is because Topo believes in making shoes that will last for hundreds of miles. Another great feature of the upper’s fabric is the fact that it is able to shed water easily.
Weight
Weight

Weight

This sneaker falls into the lightweight running shoe category because it falls under the 10-ounce threshold. Of course, this depends on the size of your foot. The men's size 9 weighs in at 10 ounces while the women’s size 7 weighs around 8.3 ounces. A number of reviewers have said that the shoe feels light underfoot despite its extremely durable engineering.
Breathability
Breathability

Breathability

The lightweight and breathable materials that make up this shoe’s upper make it a very breathable sneaker. Some say that its breathability is surprising because the upper has a little more heft to it for exceptional durability. However, the ultra-light mesh material allows for great airflow into and out of the foot chamber and delivers a second-skin feel. The Ortholite insert also helps your foot to breath a little more as well because it is designed to wick away moisture from your foot as you run.
Comfort
Comfort

Comfort

The 3-density EVA foam midsole featured in the Ultryfly 2 delivers excellent underfoot cushioning and comfort for almost any runner. Whether you are running short or long-distance or have a slower or faster pace, the cushioning provided by this sneaker will feet comfortable underfoot. The stabilizing foam on both the lateral and medial side will not be overly noticeable in terms of taking away from your comfort, rather, it will help to guide your foot correctly. The exceptionally-wide toe box always allows your foot to spread naturally and will help you feel comfortable as you run. However, if you have narrower feet, the toe box may seem a little too wide for you. The synthetic overlays featured on the midfoot area of the upper will help the sneaker hug your foot securely while the padded heel delivers adequate comfort to your heel and Achilles.
Style
Style

Style

The Topo Athletic Ultrafly 2 is a pretty standard-looking sneaker in terms of style. The colorways offered range from subtle to bright, depending on whether you are purchasing the men's or women’s styles. Because this sneaker featured a 3-density foam midsole, it appears a little bit chunky, just like a Hoka or Altra sneaker. However, the upper is sleek in design and the synthetic overlays that stretch throughout the sneaker add a little bit of monochromatic pizazz to the design.
Durability
Durability

Durability

Despite the fact that the upper is made up of layers of ultra-lightweight mesh material, it is extremely durable. Topo Athletic could have chosen to pare down the layers of the mesh in order to make the sneaker even lighter but decided to opt for a more durable sneaker instead. The layers of mesh combine with synthetic overlays to make the upper very durable while the heel provides enough cushioning and firm support to help the shoe to maintain its structural integrity. The triple foam midsole also helps the shoe to withstand hundreds of miles because it is made up of both soft and firm materials and will prevent the midsole from sagging prematurely. The outsole of the Ultryfly 2 is also very durable because it features a thick layer of carbon rubber which will reduce the effects of abrasion even after hundreds of miles.
Protection
Protection

Protection

The Topo Athletic Ultryfly 2 provides adequate protection for the every day road-runner. The carbon rubber outsole will protect your feet from underfoot debris while the triple-foam EVA midsole will protect your joints from the jarring motions during running. This is not a zero drop sneaker, rather it is a low drop sneaker and features a decent amount of underfoot cushioning so you will not have a ton of ground feel underfoot. The shock absorbency delivered through the midsole is great for any neutral runner while not being overly bulky. The upper features layers of lightweight mesh which, alongside the midfoot overlays, will hug your foot snugly and offer a comfortable and protective fit.
Responsiveness
Responsiveness

Responsiveness

The most responsive part of this sneaker lies in the middle layer of the 3-part foam midsole. The EVA foam is the snappiest of the three and is designed to flex and bounce back after pressure is applied. With that said, a number of reviewers did say that this version of the Ultrafly felt less responsive than its predecessor.
Support
Support

Support

This version of the Ultrafly offers a decent amount of support for the everyday road-runner. The anatomically-shaped footbed allows your foot to move and spread naturally while the triple-foam midsole cushions you. The under-layer of foam featured in the midsole is the firmest of the three and is designed to deliver arch support as well as lateral and medial support. The midfoot portion of the upper features synthetic overlays which allow the sneaker to hug your foot snugly and support you like a second skin. The heel of the sneaker is also designed to lock your heel in place comfortably, allowing your ankle and heel to be supported in locked-in comfort.
Terrain
Terrain

Terrain

The Topo Athletic Ultrafly 2 is designed to be worn on the road or as a light trail running sneaker. As long as you are running on firm packed surfaces you will experience a great run in these shoes. The multidirectional lugs on the bottom of the shoe are not overly-aggressive so these shoes will not perform well on highly technical terrains.
Price
Price

Price

These sneakers can be purchased for around $120 which is an excellent value considering the amount of technology and cushioning these sneakers offer. Topo Athletic does not have a very visible market presence so they are not priced like a highly visible pair of supportive running sneakers.
Traction
Traction

Traction

The outsole of these sneakers is made up of durable carbon rubber and features a number of multi-directional lugs that will help you grip the ground easily. Because these are designed to be worn primarily on the road they will offer the best traction here or on the well-packed ground. Some users did comment that they do not perform well on soft or slippery underfoot conditions.
Flexibility
Flexibility

Flexibility

Due to the fact that this sneaker features up to 28mm of midsole cushioning, they are not the most flexible sneakers on the market. However, the outsole does boast a number of flex grooves in the forefoot which adds a great amount of flexibility to that part of your foot. This is a plus because you will feel a more flexible toe-off when your foot leaves the ground. The upper is made up of ultra-lightweight mesh which will move and flex with your foot as you run. However, some users have said that the upper feels stiffer than they like.
Stability
Stability

Stability

Although this sneaker is not marketed to be a stability running shoe, it is on the higher end of stability so it is more like a stabilizing neutral running shoe. The firmest of the three foams found in the midsole will help to stabilize your foot and guide you to run more efficiently and effectively. The snugly-fitting upper will help your foot to feel supported as well while the heel portion of the sneaker will allow for excellent stabilizing cushioning and lock-down for your heel.
Drop
Drop

Drop

The Topo Athletic Ultrafly 2 is not a zero drop sneaker, nor is it a sneaker that offers an average 10mm drop. The heel stack is 28mm while the forefoot stack is 23mm which results in a 5mm drop. This is a 2mm difference from the original Ultrafly’s 7mm drop. This will allow for a slight amount of ground feel while delivering excellent underfoot cushioning.

Bottom Line
Bottom Line

Bottom Line

The updates Topo made to the Ultrafly 2 seem to be widely acclaimed and accepted by the running community. Some users did say this sneaker did not feel as snappy as its predecessor while others hailed the addition of more cushioning and support in the upper. One of the most impressive features of this sneaker is the anatomically-correct shape of it which will help your foot to sit more naturally inside the foot chamber. The wide toe box is best for people with a wider forefoot but will work well for you if you tend to have a normal-width forefoot. This highly-cushioned yet low-drop sneaker shines most in the durability department and works well for long distances as well as for slower runners. Many users did feel like they didn’t provide enough of a response for faster paces but work well for everyday runs. The added support offered in the lateral and medial sides of the sneaker work well for neutral runners but if you have specific pronating issues, you may want to look for a more stabilizing sneaker. In the end, this sneaker has been widely accepted in the running community and is worth checking out.
