Men's Ultra XT Training Shoe

I haven't tried the latest iteration of these, but I have two pairs of the previous version, the 1.5. I bought a second pair because I loved the ones I had so much that I wanted to be able to stay in them for a long time. I do crossfit in these 4 to 5 times per week. Yes, at first they are stiff, almost uncomfortably so, but they break in very nicely. I'm 190 lbs, 5'11", and I love having the stiffness for high energy workouts, i.e. sprinting, box jumps, heavy deadlifts or snatches, etc. I wouldn't choose them for long distance running, but for our average 400-1500m sprints they've never bothered me. The stiffness also makes them excellent for strong lateral movement (tennis, etc), and I just love them.

I am on my 3rd pair of these. The only complaint I have is the rubberized toe cracks relatively quickly over the first toe inset and also where it meets the outsole. My first pair cracked within a couple of weeks of first putting them on. I thought it was an anomaly, but my second pair did the same thing, but it took longer. I sucked it up because they are so comfortable. Secondly, these shoes also make my feet sweat considerably more. I'm not sure how wide the previous reviewers feet are, but mine are pretty wide but these fit pretty true to size. Previously I would have to either get a shoe size larger (14E New Balance) or just deal with it...not with Altra HIIT. They fit great and where I used to get a rub on my outer ridge of my foot and pinky toe disappeared with these shoes. I am a nurse and these shoes are my saving grace. Would have given it a 5 star, but the durability is lacking. Also, they look great in the casual setting. I wouldn't go running in these at long distances bc they are a little rigid for that, and I imaging it would tear up considerably quicker.
