Left Lane Sports has a sale going on for all their minimalist running shoes... this includes some of the heavily lugged (offroad), water-resistant barefoot shoes... I've got a pair on the way, which I'm really excited about. The Vivo Barefoot line is my favorite of all the minimalist shoe brands...
Anyway, like similar sites, you can sign up by yourself, but if you go through a referral link, you get $10 credit on your first purchase (I think it has to be over $50), and I get $10 credit for referring you.
If you want to use my link, it helps us both out.
If you've got questions about the shoes, LMK. I've tried a lot of the barefoot shoes, and am happy to answer any questions I can.
