Here on Popgadget we've featured shoe inserts, Foot Petals and Apara, both of which claim to make your high heels just a little bit more comfortable. If they aren't enough to make those killer heels wearable, then what you need are Insolia inserts. Rather than just cushioning your feet, and/or preventing them from sliding forward, Insolia actually works by redistributing the weight on your feet so that pressure taken off the ball of the foot is shifted to the heel. This makes perfect sense to me; I've spent countless hours on the crowded train, trying to balance on the heels of my shoes in a futile attempt to relieve my aching feet. Even more impressively, there are four different sizes to choose from.
