I have quite a few pairs of Sanuk sandals and loafers and just love them. These are not quite as nice. Altho the sole is comfy, it is not as thick as the yoga mat styles I have been wearing. Like the other sanuks, there is no arch support and the insole is completely flat. They have the feel of a converse shoe with the tongue and upper fitting almost to the ankle. As well, my true foot size is 7.5 so I ordered an 8. These shoes fit a little large and I wish I had gone with the 7 instead.
