Asics Gel 451 Review Facts
When it comes to competing in a triathlon, one important aspect to consider is what you will be putting on your feet. Triathalon sneakers are designed to offer excellent performance in both the running and cycling portions of a triathlon and to do so with ease and efficiency. The ASICS Gel 451 is a Triathlon shoe and is equipped with a number of features to help you achieve your triathlon goals. With its revolutionary BOA Fit lacing system, high energizing GEL cushioning, high abrasion rubber outsole, and an engineered mesh upper, these sneakers will help speed up performance and allow for a comfortable and supported ride. The shoe is also equipped with “Guidance Line Midsole Technology” which will provide enhanced gait efficiency. Some triathlete competitors will invest in separate sneakers for both cycling and running, but these can be worn for both parts of the competition. These performance sneakers were designed with triathletes in mind and are an exceptional option for anyone looking to break into, or continue on in, the world of biking, hiking, and swimming competitions.
The ASICS Gel 451 features the company’s AHARPLUS outsole material, of which the AHAR stands for “ASICS High Abrasion Rubber” and the PLUS referring to the rest of the material, which is blown rubber. The high abrasion rubber is actually engineered by mixing the same kind of rubber used in manufacturing car tires and reinforcing material resulting in a durable, long-lasting outsole. In fact, the AHAR material found in this sneaker’s outsole is the most durable rubber currently being offered in any of Asics’ sneaker models. The rest of the outsole is made using blown rubber, referred to as DuraSponge
, which is simply rubber mixed with air during its production. This blown rubber is lightweight and, on this shoe, it is protected by the extremely durable AHAR rubber placed on the high-wearing areas of the outsole.
The midsole of this is made up of SpEVA material, which is found in a number of the company’s shoes. SpEVA is made up of regular run-of-the-mill EVA material found in many running shoes combined with a bouncy-ball-like rubber. This combination results in both shock absorption and a 20% higher rebound than standard EVA midsoles. The heel of the ASICS Gel 451 boasts Asics’ infamous silicone-based GEL that provides both comfort and additional shock absorption. Another feature of this sneaker’s midsole is its “Guidance Line Midsole Technology
”. This can be seen by looking at the bottom of the shoe and is a vertical flex groove running up the center of the shoe. This groove is designed to efficiently enhance gait by decoupling the tooling along the line of progression. In other words, this technology helps your foot to perform more optimally by allowing it to move more freely on its lateral and medial sides.
The most interesting part of this sneaker’s upper is its unique BOA Fit system. On the lateral part of each shoe, you will see a circular instant release dial: this is the first part of the three-part lacing system. This dial allows you to tighten the fit of the shoe by twisting it. The second part of this lacing system is the strong and lightweight laces; they may not look like they pack much of a punch because they are very thin in appearance, yet, they are very strong. Thirdly, they lacing
system boasts low friction guides that help the laces move more freely up the tongue of the shoe. When this lacing system is loosened, the opening of the shoe is pretty wide so you are able to slide your feet in and out efficiently. The padded tongue also features a pull loop on the top to aid in easy on and off as well. The upper is made up of a lightweight breathable mesh and contains a seamless overlay beneath most of the lacing system to reduce irritation. The colorways offers are also very unique in that they have two main colors on each sneaker, but on the left and right shoe, the colors swap places giving the upper a distinctive look. On the lateral part of each shoe you will see the recognizable grid-like ASICS logo while on the medial sides, you will notice the ASICS “A”, giving these shoes another interestingly eye-catching appeal.
These performance sneakers are made up of all lightweight material; from its strong and thin laces to its bouncy SpEVA midsole. The average weight for the men's version is 7 ounces, while the women's version sits around 6 ounces, making these some of the lightest racing shoes on the market today.
The engineered mesh overlay of this sneaker gives it a highly breathable quality even with the supportive synthetic overlays. Since this is a shoe designed for triathlons specifically, it can be worn with or without socks
and has a breathable fabric lining. When you are cycling, running, and swimming, you want to be sure your feet aren’t uncomfortably sweaty within your sneakers and the Asics Gel 451 will keep your feel fresh and airy while you push your body to its limits.

and the alternating colors on each sneaker give them a unique and stylish appeal.
The most durable part of these sneakers is their outsole, made from a combination of high abrasion rubber and reinforcing material to help them last longer. Triathletes train and compete hard and the ASICS Gel 451 will hold up to the challenge.

The highly durable outsole of this shoe, combined with the responsive midsole, will help propel you on your 6+ mile run
and keep your feet comfortable and protected against the elements. Because the upper is made from an engineered mesh, they will allow water to get in, but because the BOA fit system helps the shoe mold to your foot, you shouldn’t have any issues with blisters.
The shoe-length SpEVA midsole is extremely springy and provides an amazing amount of response with each step. Unlike regular EVA which is found in many running shoes today, SpEVA is even bouncier, all while remaining lightweight. Along with the bouncy midsole, the ASICS Gel 451 also features the companies famous Rearfoot Gel Technology at the heel of the shoe which reduces shock during impact and allows for a smooth and comfortable transition after each heel strike.

and support runners like this successfully. If you have normal to high arches, these sneakers are an excellent triathlon shoe option for you.

For a specialty sneaker offering lots of great features, the ASICS Gel 451 is priced fairly. It won’t be a shoe you wear every day and it’s not made for every kind of run, but if you are a triathlete in training or competition, they are worth the price.
This sneaker’s durable AHAR rubber outsole helps to deliver reliable grip and traction. Because the rubber used to make the state of the art AHARPLUS outsole is used to manufacture tires, you can bet that these sneakers offer a great about of traction. The rubber on the soles of these shoes will grip the ground with ease in a wide array of weather conditions.
The lightweight nature of these shoes gives them an excellent amount of flexibility. With the upper being made entirely of engineered mesh with overlays to support your foot, they will be able to move gracefully with your foot. The Guidance Line Midsole Technology, which is a groove that runs up the bottom of the shoe, helps to keep the sneaker flexible as well because it allows for each side to move slightly independently of the other. This will help you take better, more efficient steps.
This pair of shoes is manufactured to keep your feet supported and stable on your triathlon runs.
