I've used these shoes a few times, but I have other shoes, so I've been using these for actual competitions. The size is 24.5cm. I've used them for about six months. These are used items, not new, so there may be some signs of wear. Please understand the condition before purchasing. The shoelaces have been changed to elastic laces, but if you prefer regular laces, I will include the original laces that are also listed in the listing.
