I have exactly that problem with every new pair of boots that I buy. Too tight at the top of my foot, gives me pins and needles and makes my foot go numb. But I find that if I wear them in they are then perfect for the life of the boot. My RMs had that problem but once worn in are supremely comfortable, and Blunnies are the same for me. Takes about a 7-10 days of solid wear to overcome the problem, and then I get years of comfortable wear from boots.
