Shock absorption
These a thin but functional and a little tricky to put on because of the thinness. They could benefit from some heft but again are functional just the same. I use during workouts since that’s when my feet are most problematic... I see a podiatrist in my future...and use socks over to keep securely in place. They wash extremely well in the dishwasher and they certainly need to be washed after each use so huge benefit to have multiple pairs.
