as i'm a flip flop man ( hate on that if you feel the need) i think my feet have a massive shock when they are plunged into ski boots, also when i bmx i have a tendency to curl my feet, kinda like trying to grip my pedals with my feet so i was thinking a similar thing could occur in my boots and therefore it could be a sort of cramp therefore leading to pinching of a nerve.
the pins and needles aren't focused on the toes it's mainly in the body of the foot.
i reckon i'll just try wearing them around the house a bit, they're pretty much as loose as they can really go without being useless as it stands.
cheers guys.
