Worth it! Love them.
Size: 10.5, Color: A-black
5 stars! For me, super comfortable and they look nice too! Soft, flexible leather and the sore is great for indoors and outdoors around the house . Thinking about a second pair for outdoor use .

Narrow
Size: 11, Color: A-dark Brown
They seem well made - but they are narrow - my feet are too wide to fit into these. Much narrower than a normal shoe of the same size

Comfort meets fashion
Size: 9, Color: A-dark Brown
I have owned a million pairs of shoes. And I am truly a rarely viewer, but these shoes are an unquestionable five stars.,These are perfect summer loafers. They fit like a glove, but do not fit tight. It is literally like walking on air and the inside is completely cushioned so you can comfortably wear without socks. They are good for dress or casual, but I like them best with jeans. They’re so comfortable I could sleep in them. Forgot price… reasonable too!
