Just got them. Quality seems extremely good. Almost as light and comfortable as tennis shoes. I reserve the right to amend this review after seeing how they wear, but so far perfectly pleased. Be sure not (not) to order anything smaller than what you normally wear. I usually need an 11.5. These are 12's and if they were any smaller they'd be a problem. As it is they're perfect. Hope they hold up. Extremely comfortable. I have probably 12-15 pairs of shoes and boots. The only thing more comfortable are very light tennis shoes, and that's only by a slight margin. These will be my everyday shoes.

Update: after a month or whatever of constant wear I like them just as much. Knock on wood.

Update: These sit on the floor next to my tennis shoes. Every single day I could reach for one or the other. Every single day I reach for these.
