use it with your Crocs (for light sports)
I wear Crocs, barefoot, all summer (with my foot doctor's enthusiastic approval), but they do tend to rub off the skin if you get too sweaty and active. I started using this product when biking with my Crocs, or taking long walks for exercise, and it works like a dream. First I had to determine where the "rub" was, but since I started using this, I haven't suffered any more blisters. Well worth the money. Washes off with soap and water and a little friction.
