You could buy an insole like Superfeet.
I bought a pair of Burton Rulers 3 years ago & 1 of them fit way shorter
they gave me a pair of Green Superfeet for free.
I couldn't see how this way thicker insole was going to help, surprisingly it did.
The bigger ridged arch, kept my foot from elongating when I cranked my boot up really tight.
Yea you can probably even get OVER half a size smaller from a CUSTOM insole. Remind suggests that their insoles (not custom) will often make shoes and boots fit up to a half size smaller.
I've been living/working in these Remind Medic
insoles for about a month now, will start riding on them next week. Very very happy so far.
