“These booties are great for surfski paddling. Thin and flexible bottom, but allows you to walk over rough ground while getting to the water, but still have lots of "feel" when steering. The velcro strap over the top keeps it snug on the foot. After trying to lots of various booties for paddling, some wear out on the sole too quickly, some have too thick of a sole causing me to lose subtle steering control. These are just the right mix. I am normally size US10.5 in most shoes. I went down a size as I'd rather have them snug than loose. They are just a tad bit short in that my toe is a bit too firmly planted in the front, but I'm still happy I went down instead of up in sizing. It would be great if they did half sizes. Also, I'm not a fan of the lime green colouring, but whatever.”
