As far as the "integrated boots" go - hopefully you mean the integrated goretex socks? I'd go with those versus the rubber boots - you have more ability to put on some nice wool socks and still fit your feet in your dinghy boots. If you have the rubber feet, you may have to find a bigger size of footwear if you want some warm socks on underneath.

We're a fan of the Kokatat, but certainly understand the price driver!
