These are a nice gray color with a pattern on the sides. I usually wear a larger size, 24cm, because I have wide feet, a high instep, and bunions. However, these fit comfortably in 23.5cm. They're a little loose. They're mesh, so they have some stretch. I only used them for one day because I needed them suddenly, so they're still in good condition. I wiped the soles, but some dirt remains. Please be aware of this. Thank you.
