With a size 12 foot (6'1" and 220), I would have bought size L, but I ended up going with XL because they didn't have the L in stock. For me they worked great over a pair of synthetic crew socks. Toasty feet in cold water - total game changer!
LOVE THEM!!! GREAT FOR WINTER SWIMMING!!!
Love the lava booties. Perfect for cold water swimming or for swimming in rocky fresh water for foot protection and minimal drag
Work great. Nice traction on bottom. A little tough to get on - but they should be so snug fit in water. One trick - pull wetsuit legs OVER the bootie - so as you swim it's streamlined and 'tucked in' - first cold water swim I did there was gap between suit and bootie - and bootie edge caught some water. Tucking bootie under wetsuit leg solved the problem :)
