These gel cushions do pretty much as you'd expect (?), they provide extra comfort for your feet. I've tried them in a pair of high heeled boots and a pair of cheap basic casual sneakers, both of which my feet can get sore in after several hours, and these gel cusions have made a difference. I no longer get sore feet after several hours of wearing less than comfy shoes with these gel cusions. They felt a little strange at first, having this slight raise partially under my foot, but after a while they're unnoticable. They stay firmly in place and are also easy to remove.
These are a great affordable option if you have uncomfy shoes that you like to wear anyway!
this is definitely a must have for any girl, These provide cushioning to help prevent the burning pain, its cool because their clear so their not as noticeable, they stay in place and the best part is they are re usable and if they get dirty you can just wash them :)
