This is the same roller derby boot as my earlier post. https://drshoe.wordpress.com/2008/08/05/skating-pain-bay-area-roller-derby-girls/
These principles would work for any sport boot including hockey, figure skating and roller blading.
Although the modified lacing I previously blogged about helped, it wasn’t enough to alleviate all the outside of the foot pain, so I added permanent padding on the inside of the boot to off-weight the painful prominences and it worked like a charm.
Just because a boot isn’t custom, it doesn’t mean you can’t customize the fit. All you need is a creative shoe repair person and you should be fine.
