Great pair of shoes
Size: 10, Color: Burgundy
I was a bit concerned that these shoes would be a bit large because I normally wear a size 9 1/2 and these are a size 10. But they fit perfectly. They are very light and comfortable. 👍

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.
