Since I've had a lot of foot and boot problems, I've gone through a lot of boot adjustments, and padding for my feet. Here's the stuff I use.
The Absolute Best Thing to Keep in Your Bag:
I avoid the cloth athletic tape like the plague, especially around the forefoot. The cloth tape is too heavy and thick. Stick with the paper tape.
Light Compressible Foam :
Designed as adjustable toe spacers, but
you can do so much more
1. Pad the top of my foot to keep my boot from rubbing on a sore spot.
2. As a lace bite pad when other other pads are too thick
3. A protective cover where a boot top rubs a spot raw. Not as thick as a gel ankle tube, so you tie the laces tighter.
4. Under an insole to give extra padding under a sore toe, or pad under a sore spot under my foot. These compress nicely, but you'll have to replace them after every few skates. They're not long lasting.
5. I've also folded a small piece into a toe spacer and taped between two toes.
Medium Compressible Foam Insoles:
Thicker and more resilient
than the light foam Toe Bandages
I now just cut them up to make small toe spacers between my Great Toe and first toe.They are the perfect width and I just tape the spacer to one toe. When the session is done I just throw them away.
Right now I've got a piece of one of these insoles as a lace bite pad on one foot. The other foot has a different product as a lace bite pad, because that leg needs something stiffer. Feet are different, they don't always match.
These are in the craft section. Sometimes when I want to place a toe pad under an insole, I use the glue dots to hold it in position so it doesn't move when I insert the insole over it, and the under pad doesn't slide out of place.
And there you are! Cheap stuff for fitting your boots!
