I have a balance disorder so I was looking for a shoe to give me extra balance support

I think all HIIT enthusiasts understand the trade-off that you have to make when looking for a shoe that allows you to squat with stability but also run comfortably. The Superrep has a high degree of stability similar to the nike metcon shoes but has MUCH better comfort while running. The burpee break was a very pleasant surprise as well, it really helps take some of the discomfort out of planking exercises.

Beware fellow wide footers - this shoe will be extremely tight in your normal size unless you remove the standard insole. Wow that made a huge difference, as the insole has a huge forefoot cushioning pad that takes up a lot of room (though it does provide great cushioning). Nike could solve this dilemma by simply making a wide/extra-wide version. Otherwise, this is an excellent shoe for the gym.
