I bought these to go in Bont skate boots (roller derby). They were an upgrade from the inserts that came with the skates BUT the ball of the insoles was too hard for me. The ball of my foot bruised internally due to the hardness of the insert and roughness of the sport. I loved the heel and arch support though. With less cushioning, the skates are much more reactive and not much energy is lost/absorbed into the insert. For practices, I am using the 2 oz miracle which is much softer and my feet are happier.
