Shoe Sizing Systems and How They Line Up

Sizing footwear is an inconsistent web of overlapping systems.  Here at GearX our products are sized by US Mens, US Women's, European/French, and Mondo point.  Just in case you think in Japanese, Chinese, or UK sizes I've included those as well.  Here's how they all line up.

Thanks to Claus Färber and WikiMedia for the sizing chart.
