Yep. The low cut at the back means I can also point my feet, as dancers are supposed to do. I found the lowness all round absolutely terrifying to start with, but now I'm used to them, I don't notice it, apart from the ease of pointing and bending at the ankle and knee.
Comfortable? Oh, you'd better believe it. Once I got used to the seriously hard top edge cutting in lower than the place on my leg that was hardened by my previous boots, I have never, ever, ever, in all my born days had skating boots this comfortable. They are not heat moulded (other than by the heat of my feet in wearing) but I call them "coaching slippers" because they are just so comfortable. I think the main reason for that is the width. They are the wide fitting and I've got space to actually wiggle my toes. I've spent months fussing about them potentially being too big, because I've been used to such a tight fit before, but now I've decided that I bloody love them and I'm not going to worry any more. I can skate in them and I'm comfortable. Happy days.
