Sizing guide — Smythe & Digby
01Measure first
Get the size right before the cut.
Every pair is cut to the size and width you confirm, which is why we ask you to measure before you order. Ten minutes with a tape measure saves a remake. Here is how, then the charts.
02The charts
Find your length. Then your width.
Find your foot length in the chart, then read across for your width. Sizes run consistently across the collection; the one difference worth knowing is that each style carries its own exact range, which the studio shows at the size selection step before you order.

Girth figures are the standard ball-girth allowances for each width at that length, in inches. Each last carries its own fine calibration, which is why the studio shows the exact range for the style you choose. Widths D and EE where the style offers them; EEE in select styles. We do not make wider than EEE.
