I am looking to rent two pairs of alpine/winter hiking boots (12 point crampon compatible) ASAP (men’s US size 11.5-12), and seeing the main suggestion online is [https://www.yamarent.com/en/shopinfo.html](https://www.yamarent.com/en/shopinfo.html?language=en). Unfortunately, they don’t carry US M 12, and only have one pair of 29s (11). I was unable to find any other physical store which rents mountaineering boots in Tokyo.
Does Montbell or another store rent? Based on Montbell’s site, they too seem to max out at 29.
