Best river/ocean shoes with good drainage & mesh to keep out small pebbles?

A new replacement pair of Salomon Amphibians? I haven't seen anything better.

Costco has water shoes right now for $20. Lots of small mesh for draining and breathing.

On their website only womens version shows up, but in-store you can find men's as well. Seemed light and OK made, but not fan of pull strings instead of laces.

I should have added – the Tech Amphibian is a flawed design so prefer a new shoe – the open heel lets in rocks which can slice your feet up. Plus I find they can run narrow.

Found the Columbia Powervent which has mesh all around and should be more protective. Seems you can find it for only $48 now too. http://www.columbia.com/mens-powervent-BM2592.html

Also found a kayak shoe at NRS, called the Crush Shoe – looks very durable with drainage but not as breathable (little mesh, though upper made of nylon): http://www.nrs.com/product/30043.01/nrs-mens-crush-water-shoe
