Jolt: I don't know of any retail stores in the US that are carrying the Feelmax shoes. They have just become available in the US this year. There are a couple of US online stores that have them. One is an oddly milataristic-looking site: Extreme Outfitters

I got them from directly from Barefoot Ted, but now he seems to just link to the other site.

You can get them also from Gifts From Finland. They also have an Amazon storefront.

If I hadn't found these, I probably would have gone with my old neoprene kayaking booties. I figure I can also use these in the spring or summer for triathlons, although I would like to be able to run truly barefoot next summer
