If you find yourself renting, borrowing or browsing for new gear (especially online), it really helps to know these numbers. Not a definitive list:
- Your DIN. Good to know the value rather than trusting your buddy to get it right.
- Pole length. Everyone has a different idea of how to measure these days. Why trust someone trying to make a sale?
- Mondopoint size. These differ wildly from maker to maker and from boot to boot, but it's still a good place to start.
- Boot sole length (in millimeters). Good basis for comparison, good way to ballpark a binding setting without the boot itself.
- Boot volume (in millimeters). Sometimes hard to find out, but really useful as a starting point for trying on new boots.
- Flex index. The worst metric for measuring boot flex, except for all the others. Better to know it than not to.
- Old-fashioned glove size (in inches). Way more precise than S-M-L; only reliable way to buy gloves without trying them on (using a chart).
- Ditto head measurement for helmet.
