I found these awesome GreenToe shoes at Ross for $15, when they are normally $90 online! Yes, they are hemp. And the soles are repurposed tires. And they are super-comfy. Oh - and you can pull out the inserts and wash them if you have stinky feet like me!
The GreenToe website is here.
(yes, that's Buddy Beagle's belly behind the shoes)
