Pretty much the perfect work shoe. Simply put quality is much better and they fit was right on. These slippers are warm and comfortable to wear. I am 52, weigh 165, with mom hips. I take a size 9 and other keen sandals Ive bought in the past in that size were a little tight and took a while to break in so I could get them on easily. I should have ordered an 12. I first tried them out in San Francisco traipsing around the hills. You may find yourself feeling like a beta tester, it can get pretty frustrating. Im 63" at around 260 and these fit just fine. However, just know, that once you build it, it cannot be broken down or adjusted in length.
