I'm selling these boots because I've used them twice, but they don't fit my feet. They're practically new, as I've only used them for a few hours! I hope to make a deal with someone who understands. These are Japanese-original boots that achieve superior ski control and a high level of precision, comfort, and foot wrapping for expert skiers. The recently introduced FORMULA series are lightweight and comfortable heat-moldable boots. Of course, the width can be adjusted, but the most distinctive feature is the moderate fit of the upper shell. Details: Even if you have a lot of volume in your calves, you can wear them with a reduced forward lean angle. Depending on the model, HEAD's unique Liquid Fit technology can improve the fit around the heel. These are ski boots with a flex of 110 for intermediate to advanced skiers, shell/inner compatible. - Brand: HEAD - Model Name: FORMULA 110 - Flex: 110 - Suitable Level: Intermediate to Advanced - Shell/Inner Compatible
