We purchased these wonderful sneakers in Europe and my daughter outgrown them too fast (she used them just for indoor sport activities due to non slippery sole). I copied the info from their website and you still can purchase them in some online stores for the full price.European size 36 converts to US big girls' size 5 or an adult size 6.5 - 7. The interior length is 9" (23cm).The only flaw is missing the end of one shoe lace.Comfortable and practical women’s sneakers made of eco-friendly “breathable” material with an antibacterial effect are perfect for hot days. The neutral beige style is complemented by perforations for better breathability and thick lacing. The soft tongue and back do not rub the foot.
