Positive
  • I work as a podiatrist and when I got these I was very impressed, the toebox is wide enough but not sloppy, the support in the shoe is nicely engineered, the protection is very good and as for comfort….perfect.
  • I have feet like a duck, all shoes hurt but these work really well for my odd feet, no friction, aches or rubbing and lots of cushion and support, finally a shoe which lets me run comfortably. I’m hoping these last.
  • My feet are wide, hammer toes so the toebox in these are a dream come to true for me, width is also perfect, lovely cushioning, nice traction and top support from these.
  • I love the )mm drop in these it is fantastic, I prefer minimal padding such as I get from these, I’m a mid foot striker and can run as long as I want in these without a single problem, these are a 5 star running shoe.
  • I find a perfect balance between cushioning, support, Width, shoe length and very supportive heel cup, very nice shoe and I put in twenty miles each week in these.
  • These are better than the 2.5s, it’s great to go back to the original shape of instincts, the materials are improved, toe box space is much better, I am delighted that Ultra has gone back to what works for my running.
  • These are simply put a perfect shoe and fit, width for me is nice as I hike regularly in these on weekends, the support, cushion and especially the grip are exactly what is needed.
  • These are now back to the original features and standards so I got a pair and ran in iron man and did very well, fantastic shoe, very reliable.
  • I get lots of wide feet problems but these are nice, very good fit, Took me awhile to settle in using the low heel but I like it. All the features in this shoe are spot on for good running.
  • Use these for the gym, might sound off but these are seriously good for GYM and outdoor sports, love the support and spring in these, wonderful discrete cushion and all the support anyone could want
Negative
  • I don’t ever over pronate but looking at these even I had second thoughts. Wearing very badly, bits of the sole pealing away, with these if you put in serious running they start to disintegrate fast.
  • Far too tight over the top of my feet, I have wide feet but I got these because they are meant to be wider. The shoe feels loose in the wrong places and tight in the wrong places, sizing is terrible.
  • These give my arches a lot of aching which means too much arch for my feet, the rubber by the right shoe toe area is peeling away in just 5 weeks, I am thinking these might be fake because I used this brand for years without any type of problem before.
  • Mid foot just to thin but lots of room up front? This is a strange design, my arches cannot flatten, and natural foot movement is too limited.
  • These have the highest arch support ever for a medium style shoe, lots of discomfort, also the fabric internally is already shredding to bit, not a good shoe at all.
