This about my 6th pair of Sanuks, and they have met all expectations. The yoga mat foot bed is the most comfortable I've ever seen. I wear flip flops and Side Walk Surfers exclusively year round, because of this, comfort is a must. I've worn all brands of flip flops, and Sanuks are the most comfortable brand available. The only downside that I have seen for the yoga mat foot bed is that if you wear them like I do (in all environments, including fields, woods, etc.), sometimes they do not hold up as well as a leather foot bed will (that's what the "Fraid Not" and "Fraid Too" line are for).  Despite this, though, the comfort of the yoga mat flip flop makes it well worthwhile. I have pairs that are 3 years old and still as comfortable as ever. You cannot go wrong.
