I wear size 10 men, what size socks do I need?
ROBERT B i ordered the same as my shoe size and they work fine vin my drysuit boot
JEFFERY J F i wear just over size 12; XL sock works for me
DANA K I wear a size 13 men's shoe, and they fit just fine. The socks are great and make putting on my wetsuit (and taking it off) much, much easier.
My suggestion would be to put the socks on before putting your wetsuit on and, at the end of the dive, leave them on until you remove your wetsuit. I think you'll be pleasantly surprised as to how much easier it is to put on and take off.
MARK S If you are using sock in full foot fin, get a size smaller (9) so you will not have the sock slip when you don the fin. If open foot fin, then get size 10.
RICKY N I believe I purchased a large and it fit perfectly, but your experience may be different than mine.
