Lange RX Heritage

The RX Heritage from Lange is a men’s piste race ski boot designed for groomed-slope skiing with an emphasis on precision and control. Its low-volume fit and stiff flex make it suitable for skiers who want a direct connection to the snow without extra bulk.

This boot features a 97 mm last that brings your foot close to the shell for a snug, responsive feel, while the 140 flex index delivers firm support for quick turn initiation and stability at higher speeds. At 2 220 g (size 26.5), it balances solidity with a weight that won’t overly tire you out on longer days.

The flex rating of 140 places the RX Heritage firmly in the performance category—stiffer than a comfort-level boot—so the shell resists bending under strong pressure, giving you more counterforce and detailed feedback through your skis. The 97 mm last refers to the internal width at the forefoot, meaning a narrower fit that many racers and precision-minded skiers prefer for sharper edge control.
