My 27 Raichles were definitely too big, but I was coming off a pair of 26.5 Oxygens that I had to ride with my toes curled. These ones seem snug, but a little bit of wearing them should definitely help.
I haven't tried any other Kryptons, but these ones are very soft from what I was told, and now having tried them on, I can definitely confirm that. However, that may change once I actually ride them.
