Propa Heat Molding

Custom fit your ski boots - right from home.

Whether you're molding liners or reshaping both liners and shells, the Propa Heat Molding system gives you everything needed to achieve a precise, high-performance fit without visiting a shop.

Inside you’ll find the tools to heat, shape, and fine-tune your boots with confidence. Using controlled, liner-safe methods designed for consistent results.

Included:

• Two pairs of Propa Merino Ski Socks
  One pair worn during molding for even compression. The second used as a controlled heat source (rice-filled and microwaved) to deliver safe, consistent warmth to the liner.

• Targeted foam fit components
  Designed to relieve pressure and shape key problem areas during molding for a more precise result.

• Step-by-step instructional video
  Clear guidance to walk you through the process from start to finish.

When you're done, you’ll still have two premium performance ski socks ready for the mountain.

Important: Not all ski boots are heat moldable. Always confirm compatibility before beginning.
Careful temperature control is essential - overheating or prolonged heating may damage your boots.
Heating performance can vary depending on your oven, so monitor the process closely at all times.
