Size M (23.5-24.0cm). Width of instep: 8.2cm Sole height (front): 5cm Heel height: 10.5cm Shaft height: 12.5cm I've worn these about 3 times, so please refrain from purchasing if you are concerned. The square toe design is relatively less stressful on the feet. Also, I usually wear 23.5cm, but they fit perfectly with insoles. For your reference when purchasing. Color: Black系 (Black-based) Material: Faux leather
