Blister in the Sun

So my post about my shoes with laces... What I didn't mention is that almost every one of those shoes gives me blisters. The boots absolutely obliterated my feet. Many, many battle scars.

I think I am more prone to blisters than most, which is unfortunate given that shoe-buying is one of my hobbies. I get blisters just looking at a pair of shoes...Recently after a bone-chilling hobble (in flats, no less! Flats that I've owned without major problems for 5+ years!), I resorted to the "Washington D.C. look" for the commute home.

Now that is giving up.

Anyone have any suggestions? Does Blister Block help?
