Teva Zilch Big kids Pink listed EU 36 US 6. I'm not sure how these relate to big kid sizing but I'm a EU38 US 7.5 and they were a bit big on me. My foot measures 24 cm and there is definitely room for growing. Look to have been used very minimally. Probably belonged to a kid who outgrew them as the soles have initials. These are zero drop with a little cushion. I bought them for hiking but they fit me too long and overall too big volume wise. Best for med-high volume.
