Tried on only. Available for immediate purchase. The material is a light, Crocs-like material. The website states the foot length is 17cm. For my daughter, who usually wears 16-16.5cm shoes, they seemed to be about 1-1.5cm too big. There are two outer buttons, allowing for adjustment of the ankle size. The heel is about 1cm. The toe design is also wide, so I think they can be worn by those with wide feet. - Color: Beige - Strap: Yes Thank you for looking.
