i just walked around outside with my vapour barrier socks for 40min. seems fine but something weird happened. most of the purple on my big toe disappeared and now i'm left with a ring of purple bifurcating the the frostbitten area and the non frostbitten area. i'm interested to see if the purple returns or wearing the vbl warmed my toes enough to provide greater circulation and flush the blood.
so, i'll try climbing tomorrow. i'll need to be hyperaware of the warmth of my feet. i think if i froze my toe again with the vbl it would be bad, bad news.
