I hope you’ve already read through my initial review of SportShield. As I mentioned, we received samples of two products, BlisterShield and SportShield. Both products are from 2Toms, both designed to reduce friction during training and races.
I don’t have serious blister issues in my current shoes, the Saucony Stabil 6. I do, occasionally, get a blister on my right foot after running 6 miles or so. Normally happens if I tie my shoes too tight and don’t allow any room for my foot to expand during the run.
I followed the directions for BlisterShield, adding the powder to my shoe and shaking/rubbing it in to ensure good coverage. The first time I used it, I didn’t get the powder dispersed well and noticed a bit of a buildup in my sock, just under my toes. The second time, I spent a bit more time getting the powder worked into my sock.
I tried BlisterShield in two types of socks, cotton and technical. I used BlisterShield on a rainy day and on a dry day. The results were similar both times. I could feel the powder in my socks, not uncomfortable, but very different. On the dry day, the feeling was very similar to using cornstarch or body powder in your socks, but I felt the BlisterShield working for the whole run, not just until I started sweating as with cornstarch. The results were the same on the rainy day. I noticed reduced friction in my socks, no hotspots, and no blisters.
As I mentioned, I don’t have a huge problem with blisters, but the friction reduction was noticeable. We’ll publish a full review soon, with multiple reviewers and more tests.
