Josef Seibel slip on sneakers-Worn 1 time

Gray, side zipper, slip on sneakers. Size 8, EU 39. These were a gift and ended up being too big. I’ve got a very narrow heel and Achilles’ tendon and these slip off with each step. They are extremely comfortable shoes and a great neutral colored gray that goes with everything. I don’t have the box they came in because I traveled home on a plane and tossed it after they were given to me. Otherwise these have only been worn once. They are in very new condition.
