Most comfortable shoes, right out of the box!
Size: 8.5, Color: Cognac Napa Leather
Oh my! So, my ordering of shoes online has been hit or miss - 1/2 size too big or too small; too wide or not wide enough. Enter these Marc Joseph shoes… such a game changer. They fit like a glove, exceptionally comfortable, and easy to slip in and out of. I like them so much that I am shopping for another pair. So far, the size, quality, fit, feel, look, and comfort make this pair my dedicated first pick. Btw, I have been wearing them for six hours and they are still very comfortable! I highly recommend these shoes.

Worth the money
Size: 11, Color: Tan Faux Leather
Ok these shoes are not Farragamo shoes. They are a little more footballish in texture, but they are very decent quality and they fit actual size. Wore them to drive 6 hours and they were comfortable and didn’t make my feet sweat. Later I wore them out walking bc around town and although the don’t have rigid soles, they were quite supportive and easy to walk In. I just wanted basic shoes that didn’t have plastic looking leather. I would purchase these again but note they are not Farragamo.
