Replying to Are my boots too small...ways to fix this

Hey NS, looking for some well-educated opinions here in regards to my new boots. This season I got fitted to a 26.5 Dalbello Krypton, after coming out of 27.5 SPKs in which my feet were sliding. They were pretty snug, but I was told and thought myself they would pack out. Well, after two full days of riding, they haven't seemed to budge much at all. The big toe on each of my feet was absolutely killing me by the end of each day. Separate from this issue is that the right boot seems to be cutting off circulation to my foot from being too tight on the top, even though I have the bottom and middle buckles as loose as they can go. Looking for input/solutions that might help me out here. Would custom footbeds help this at all? Thanks
