As mentioned, order 1/2 or 1 full size smaller as they tend to run large and you need to fit snugly in athletic shoes. I usually wear a size 9 in street shoes, a size 8 1/2 in trainers, but I ordered a size 8 and they fit perfectly. crouch to be stable. Ideal for those with an awkward calf-to-thigh ratio, so the raised heel helps compensate. The tarsal strap provides extra stability and confidence during lifts and can be easily released after each exercise. I mainly use them for squats, lunges and pushes. In terms of durability, I've had them for about six months now and they're holding up great. I only use them on leg day, and if I need to do cardio in the same workout I bring other shoes. I didn't notice any compression on the high density foam heels. These are specialty shoes, so I don't recommend using them for cardio or exercises that don't require specialty shoes (bench press, deadlift, machine work, etc.). .). Definitely don't wear them to the gym, they're built for stability, not mileage. Take care of them and they will take care of you.
