But - if you were not trying to "heat" your feet and were just trying to maintain body temp what would you think?
If it is cold out and you don't notice your feet are "not" getting cold - would you consider that as success?
I dont regret buying them, its springtime now and the temps are a little warmer, so I think it might be a little unfair to keep trying to evaluate them.
On the first two occasions I wore them it was pretty cold and I did have freezing fingers, but my feet didnt suffer from cold, so from that perspective I would you consider that as a success, what I think we need to prove now is there longevity as most of the previous "sales revues" said that they stopped working after a few uses!
