Amazon Verified Purchase I've been running short distances on uneven terrain (5K trail races), with 3-5 mile training trail runs, and have been having trouble with a hot spot on my arch. Was getting a blister there every time I ran more than 2 or 3 miles, whether out on the trail or on the treadmill. Tried Body Glide Anti-chafe first, didn't help much. But this stuff worked for me. I put it on fairly thick and don't really rub it in (wish they provided directions...), then wait a few minutes before I put on my sock. It's pretty creamy, and I figured my sock would rub it off or absorb it (and when I take my socks off, it doesn't appear to still be on my foot), but whatever happens to it after I put the sock on doesn't seem to matter, as it really takes the heat out of that spot. I haven't had any new blisters since I've started using it. Just ordered a few more. Keeping one with my race stuff and one by the treadmill.
