There are three types of boots, rear entry, overlap and mid-entry boots. The rear entry is easy to use and also the cheapest. Overlapd and mid-entry boots are more expensive but they are for better ski control and better for fit and performance. When buying boots,t he fit is the most important thing. A good fit should feel like a firm handshake. You want to try them on and walk around until you are fully satisfied.
