Euro size 27. This model is not sold in Japan. My feet got a little bulky for Superfit Storms, and Asics felt too loose around the ankles, so I switched to biomechanics for my outdoor shoes. I looked for indoor shoes from the same biomechanics brand, but there were no white mid-cut shoes in Japan, so I imported them from Spain. Used for less than six months. Because they were a taller type than the outdoor shoes listed separately, I wore them with a special insole on top of the original insole. The shape of the insole remains, but it hasn't touched my feet directly. The material is synthetic leather, so it cannot be washed, but the insoles have been washed and the shoes have been wiped clean.
