Ladies, don't be afraid. Buy 'em. Trust me
Size: 9.5, Color: A Black
My elderly mother adores these. She had to have breathable awesome shoes for post-surgery and these fit the bill (and her feet!)
So i got some for me. Whoa. Comfort! And I love the slip-on ease, b/c sometimes I just need to go, go, and go some more. Love them in black, haven't had long enough for durability, but helpful for my mom in her physical therapy and they're holding up to the worst she can do to them.

Good overall shoe, great for basic needs
Size: 12, Color: A Black
These are nice shoes. I put $40 arch support insoles in mine, so I like them even more, but they were fairly comfortable even without. They fit well, though slightly large, and seem to hold up well. No real complaints, though made a bit cheaply.

Great walking shoes
Size: 11, Color: All Black
A very comfortable walking shoe that’s well made and looks like it’s going to hold up well for everyday wear. Lightweight indeed and probably doesn’t require much cleaning. Easy to get on and off without much stress though.
