Aggie, good luck protecting your blister. I used to get awful blisters in my arches. If you can't find NuSkin, I used to find that just a plain 1" band-aid with a little Neosporin on the pad as lubricant was enough to protect it.
What are you using to prevent those blisters? I never did find out why I was getting them, but I started using BlisterBlock on my arches before every run (also heavier wool socks), and I haven't had a blister on my arches since. I've been a little nervous since I've been trying to increase the mileage, but so far, so good.
I'm feeling a lot better, but still a bit weak. I'm going to try to get out for a little jog here before my massage (re-scheduled from Tuesday). Can't wait for that!
