Rockstar is an understatement. I have skis for feet and this fit great. I went into the shop and they helped with my fin return. Super nice and very informative. I would highly recommend this brand and the 662 shop.

A Must Have
These fine socks are a must-have. They’re extremely comfortable and soft! I’ve had many variations of the fin sock over the years, and these are my favorite. The best part is how the Velcro around the heel strap of the fin. No more fumbling around for loose fin socks in my bag or having to wrangle both the fins and socks after a session. Plus the Velcro adds a little more smugness to the fin fit, meaning tethers aren’t necessary.
