I have an old pair of Burton Moto boots size 11 (29). Have a few scratches but are still perfectly functional and all the tightening strings are intact.
They don't smell at all either.
Rather than throw them away or have them lying around it would be better if someone can use them.
Anyone wants them I will send them to you. Chakubarai or pay on delivery. Probably about 1000Yen.
