This is my second pair of Teva Toachi sandals - I really like the buckle instead of velcro for securing the over the foot strap - don't have to worry about the velcro getting dirty and the fit is the same with the buckle.  I wore the first pair out in three years of pretty heavy use on trails and around town, in the water and in the rocks - they lasted as expected.  Not so sure about this pair - they are very similar in construction but not the same.
