This document provides instructions for selecting the proper snowboard boots based on a person's measurements and skill level. It outlines the following steps: 1. Measure both feet and use the longest measurement. 2. Estimate boot last and flex requirements based on weight, height, and skill level. Shell modifications may be needed. 3. Check the sticker on the back of the boot to confirm the flex index range, last number and color, and model name match the estimated requirements.
