Got it after a dozen other slip ons that my feet can't even fit in (probably made for locusts). These still work well for my 220 pounds and heavy use. I definitely recommend it. PS Getting on and off is easy and they don't fall off.
Pros
Waterproof, easy to put on and a Christmas present for dad. Wish it was half the size
Cons
Shoes can get hot in warm weather, causing discomfort and sweating.
