This stuff is great, it’s flesh colored first of all, but you can put it wherever you need it. I use it when Hiking, or wearing a pair of heels that may pinch a little at the toes, it adheres to the skin, but is a soft fuzzy material on the outside, so the shoe, sock whatever will not stick to it or move it around too much. Hope this helps!
@crazyprincess I have the same problem, I wear a kids size 2 and have really high arches… Check out http://cinderellaofboston.com/ They specialize in small feet and you can fax them an outline of your foot and they will recommend the right size and fit for you, prices are good and they have great stuff, but mostly sandals, dress shoes, high heels.
