Review on ENGO Rectangle Blister Prevention Patches: Ultimate Protection for Boots, Skates, Cleats, Helmets & More (2 Patches) by James Wickware

Really impressed that they really help. I used to get severe blisters on the balls of my feet after just one walk. With their application on my insoles, my feet will be saved. I was wondering how the product concept could work and the answer is that this area of your shoe feels a bit slippery/slippery so your foot slides over it and doesn't create friction. So easy! I used to feel like my legs were on fire. Now I feel good! Hooray! As for use, one of the large rectangles, cut in half and slightly trimmed, fits perfectly in the balls of my feet and I always have the second on hand when they are worn out. But after almost 2 months of daily walking and regular gym visits, they're still going strong and I haven't had to replace them yet.
