Upsize ½+ size for optimal fit. (e.g. If you’re normally a size 9, order 9.5). Scarpa boots are sized as a mountaineering fit, which feels ½+ size too small when compared to a normal boot size.
If your measurements are between sizes listed in the chart, select the next larger size. (e.g. If your foot measures between 9 & 9.5, order 10). All boot sizes fit an average foot width.
