As soon as I saw these, I just HAD to have them! Definitely not what I was shopping for, but I just fell in love. I wear them daily for work, long shifts on my feet as a vet tech. I was a bit concerned about my feet slipping out, but have had no problems with this, even though they are about a half size too large. I needed a 10.5, but they only came in 10 or 11. 10 was definitely too small! I wear them with socks for work, and with socks or barefoot for play, and have had ho problems with blisters, although they do slip a bit barefoot due to the large size. As always with Merrells, they needed no break-in time. They have nice traction in muddy dog walk areas and on wet floors. I've receive complements every time I wear these and I have convinced my boss to give Merrells a try because of these lovely shoes.
