Chris......I ordered the biggest size they have...15! I have a 15 foot. They were plenty big enough for the neoprene socks and very comfortable! They were absolutely fantastic on the rocks with the spikes on! Great ankle support too! Highly recommend them!
i bought actual boot size- with a 2 mil neo sock they're purrfect. wanted a good fitting boot for wetsuiting. if i were to wear them with my waders (5 mil booties) i would go up a size.
