Relative to other sandals I own, they are very lightweight. The minimal weight, minimal strapping, and soft cushy footbeds make it feel like I'm standing on little clouds.  They seem like they will be good for standing and light walking, but for trekking around alot or doing work where you push against the shoes you probably will find them to be not substantial enough.  I think they will be great for driving around going to stores, doing errands, stuff like that. For yardwork or walking the dogs I will use one of my other pairs.  Cant comment on durability as I've only had them a short time.  They seem to be a bit wider than I was expecting but it still fit ok.
