These are really good to have, a must-have! I wear heels a lot, and it usually isn't a problem for me, but even so, these are simply a must-have. Even if you're like me and you don't have a problem wearing most heels, these just make things more comfy, sometimes much more comfy! The thing is, the higher the heels, the more of your body's weight is being supported by the ball of your foot. These gel inserts really cushion the ball of your foot against the sole of your shoes. As we all know, some high heels have little, if any, padding on the sole at all, which i've always wondered about. Well, these make a very noticeable difference. I personally love wearing three and even four inch heels, I think they're very sexy and fabulous, and using these gel inserts always makes a big difference.
