text: I bought these in a D width just for my left foot because while I love these running shoes & have been running in the Minimus for years, my left foot keeps blistering on the inside edge. I wear injinji socks, use body glide- I've even tried double-socks. Nothing helps, but I don't want to switch shoes because everything else is perfect for me. So I bit the bullet & shelled out $$ to buy another pair just for the left shoe to be wider. But the sole is exactly the same-- only the upper is wider. It's not the upper that keeps rubbing the inside of my foot!! It's the edge of the insole!! So I'm frustrated & still have a blister in the same spot :( Otherwise, great minimal shoe.
