I went to a Moosejaw brick & mortar to pick up my pair. It seems like this style runs a little small. I wear a 10 or 10.5 in regular sizes and ended up in a 44 in these. The employee said my feet were "wide" which I would have to disagree, but for the purpose of the five fingers it makes sense now.They are incredibly comfortable and truly feel like you are barefoot. Even wearing them for long hours doesn't leave your feet feeling and/or smelling gross.
"Buy this product to feel barefoot when walking around. They are very nice and look cool!"
These shoes are great looking and I love the red and black. My problem was after measuring my feet several times in a day, and following the size chart, the shoes were still too small even though I matched up with the size recommendation. I suggest buying two pairs of shoes and returning the less fitting one.
