So Solid
"Give any shoe an extra edge of both support and cushion. I use these in full boots, approach shoes, and even modern soft running shoes, which I sometimes wear on the mountain if I know the loads will be light. These really do transform shoes. They add significant cup and structure to the heel making it much easier to get that locked in feel. They add all day comfort to the forefoot and all around cushion. Have them in 3 different shoes now."
