KUDOS Silicone Plantar cushions!
I used these several years ago on trip overseas. LOVE THEM!! Totally forgot about them! I can wear them in almost any shoe! The soles of my feet don't have much tissue, so bone pressure on bottom of my feet can be very painful! Hence--Great relief for ball of foot pain. I forgot about them until recently--and sooo happy to find them at Footsmart! I keep 4 or 5 pairs on hand, and can wash in sink with gentle soap--then dry on dry towel overnight. ( I don't put in the dryer!) I can use these in almost "any" shoe. I had given up on sandals--but now I can enjoy wearing them again. I don't usually wear heels--but may try with a modest heel now too!!! BRAVO!!
