I took a chance and ordered three pair of men's Merrell barefoot shoes. I loved the styling. Here in the desert, every pricker goes through the netting of most styles, so I wanted something as closed as possible. Normally I wear women's 7 1/2, but in the barefoot style and B they are too short and narrow for me. I ordered the men's size 7 D. They are a little roomy, but very, very comfortable. I love these shoes and wear them constantly, grey for the desert, brown and black at work.
