Ok, I didn't get them for $70, but I did have a couple pair of different sizes arrive today and I am delighted. I'm a pretty exact 9, and with a 4E socks + my nicely fitting crushed neoprene socks, I fit pretty perfectly in a 10 Wide. I may also take the footbeds out as it adds a bit of room.
The thing I really love is they aren't too big that I can probably use them as normal footwear for traveling. If I wanted to go on a hike I could see wearing these instead of the flip flops that is usually the only footwear I bring on trips.
