Perfect fit, very soft for 5km and more but at the same time extremely stable. Grips my leg just like it will separate from my leg when I tie my shoelaces. Also extra holes so you can lace it up nice and close to your ankle, the tongue is long and comfortable so the laces don't cut off blood circulation! The 4mm heel-to-toe heel is ideal for a correct landing. I also do CrossFit and couldn't find a better shoe for a few workouts. Falling from heel to toe also helps me with squats. The shoes are wide, flat and stable enough to perform Olympic exercises! I can do everything in these shoes, great cushioning for box jumps and double jumps, these shoes can be used as running shoes. Much better than other CrossFit shoes because I can run 3+ miles in them unlike other CrossFit shoes. Although these shoes are not designed for that, I can use them for more than just racing! Great shoes!
