I bought a pair of 5mm internal split toe boots size 11 and theyre too big for me. I wore them yesterday for the 1st time, and they are really warm, and that ''flashdry" technology really does work, the water just falls off the neoprene. Anyway, i wore them for a 2hour session, realized theyre the wrong size. These are so warm you can easily wear the 5mm through the coldest **** New they are $65 and I'm selling for only $40 so this is a deal. I'll meet up with anyone in the south jersey area.
