What looks like a nice design with a sturdy sole turns out to be uncomfortable.

* The fit is small/tight. I wear a 10M in many shoes, 10.5 in athletic shoes. The 10 here fits like a glove. Putting it on wet feet would be a challenge. With no half sizes, going up to an 11 seems excessive...

* No arch support. Despite the molded rubber sole, there's no arch support at all.

* Fairly minimal drainage. Since there's not much drainage along the sole or in the footbed, you're going to be squishing around.

* The kicker: An abrasive, itchy seam right over where the big toe goes. This is not a shoe that's meant to be walked around in, or the designers never actually wore a pair. I always wonder how much glaring defects get past the QA that all large brands should have.

If you're engaged in light water sports, sitting in a kayak or canoe, maybe tubing / rafting? These will work fine, and they're nice looking shoes.
If you plan to wear them any distance, keep looking-- these aren't as comfortable, well-fitted, or well-drained as you want.
