Booties are the bomb
"Awesome"
Perfect fit
"Perfect fit! I'm an 11.5 in most shoe brands, got 11 size for these, and I'm pretty sure 10 would have been a mistake. They do take on a bit of water, so I should probably drill a hole but meh. Now to see how long they last."
warm feet=good session
"After 1st session, booties worked well. Concerned about the size but seem to be the right size for my feet. Looking forward to many days of surfing."
