description: "Many shoe size charts list the inner insole length, while shoppers measure their foot. Side by side, the two look a size apart and shoppers order the wrong pair. Green13 Size Chart knows the difference: tell it what your chart measures and it adds the fit allowance. Shoppers enter their foot length, or the size they wear in major sneaker brands, and get the matching size in your chart. Start from a template and assign each chart by product, collection, tag or vendor."
