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 :)
I recommend these highly. My shoe size is between 9 and 10 sometimes 10.5. I purchased a size small and a size medium because I wasn't sure which one's I would like more. I actually liked the fit of the small better, but the medium would have been fine too. I just went swimming today in water that was around 50 degrees. I double layered these (small first, then the mediums over that). I couldn't feel the water temperature on my feet whereas my bare hands were really cold. As soon as I got home, I ordered three more pairs. Next time I go swimming, I will try this with a single layer and try to remember to report back about how that felt with cold water.
I love my booties for winter ocean swimming in Florida. My friends and I wear your lava booties with our Churchill pro fins to keep our feet comfortable and extend our swims in colder waters. I highly recommend them.
