Finally the chill is gone from my toes. I surf, I can't have numbing feet, this did the trick. My 3mm booties that I bought at Dicks, we cheap and not made for real surfers. I wear these now surfing in 52 degree water. Great customer service at pleasure sports, highly recommend them. I live in CA and don't have to pay tax because they are in FL. My whole package cost me about $380 and I saved a bundle just on tax.
