Fantastic purchase
Size: 12.5, Color: Black
Fantastic purchase. I had a trip to Spain planned and wanted shoes that would work both for lots of walking and also more dressy events so I bought these. After a nine day trip to Spain, walking over 20,000 steps a day through cobble stone streets I can report these shoes held up, were comfortable, gave no blisters, and all with virtually no break in time for the shoes. I wear a size 12 but bought a half size larger and it was a perfect fit. Definitely recommend these.

If you’re going for cushion and looks, these do it.
Size: 9.5, Color: Grey
These are massively cushiony. They fit as sized, slip on well, and look very good. It seems like they should hold up well.

Nice and affordable, but poor arch support and mushy insoles.
Size: 11 Wide, Color: Black
These shoes look nice and feel comfortable at first, but the soft memory foam type bottoms on these don't provide enough support. I am a big guy and find that over the course of the day the insoles compress and my feet end up at an angle. After a long day on my feet, my dogs are barking and my leg muscles are tight I think from walking on an angle. I added my GoodFeet arch support and they help a little with arch support, but the insole is so soft that it absorbs the bulge quite a bit. If you're skinny and need a decent looking pair of shoes on the cheap, they might be ok for you. I would not recommend long walks or strenuous activity in them. I will say they are lightweight, breathable and a decent value if you don't have flat feet and a beer belly (I don't even drink beer, how'd that happen, WTH?!)

Love the shoes.
I love these shows. Super cushioned and comfortable. Makes casual but professional dress so easy. Buying different color because I like them so much. They are true to size. Maybe a tad short in toe box.

Stylish, Comfortable, and Great for Everyday Wear
Size: 11, Color: Grey
The Marc Joseph New York Men’s Edison Street shoes are a standout — stylish enough for work or a night out, but comfortable enough for daily wear. The hands-free technology makes them easy to slip on and off without sacrificing fit or support. They have a polished, classic look that pairs well with both casual and dressier outfits, and the comfort level stayed high even after a full day on my feet. Good quality, flattering design, and a versatile choice if you want shoes that look sharp and feel great. Would recommend and buy again.
