I'm also in Edea Choruses and I'm normally a mens 6.5 in UK sizing (I have teeny feet for a guy), but when I went to buy my Choruses then they didn't have any of those sizes in stock so they suggested I try the size 6 (260) that they did have in stock. They fit and were rather snug but I didn't think anything of it and bought them anyway because the journey of getting to this point had been kinda arduous enough as it was.
Got on the ice first time in them... All good... Half an hour later and my big toe on my right foot (larger foot) is chafing pretty badly and I can no longer feel my heels. Since then they've broken down enough that I no longer have either of those problems anymore, but every single coach I've ever shown my skates too thinks they're not done up tightly enough, which is fundamentally because they're a bit small for me. A part of me wishes I'd stuck to my guns and gone for the 6.5 size, but I'm here now and I don't feel like it's done me too much harm, if any.
