- Brand: MBT - Size: 36 (US 5.5, UK 3.5, MM 240) - Color: Black - Design: Wingtip style - Insole: Cushioned insole - Material: Leather Thank you for viewing. I usually wear a size 23.5-24, but these are smaller than the listed size. I think they would be a good fit for someone who wears a 23-23.5 size. They didn't fit me, so I only tried them on, and they are almost unused. I am an MBT user, and I recommend them because they don't put a strain on your legs and back.
