I can't believe nobody else uses these. I have a boot sole length of 318mm, and the villager XXL is a perfect fit. If you have really big ski boots, you might be out of luck. These overshoes are perfect for so many reasons. The rubber soles provide unreal traction, so your not slipping and sliding on your running boards. They also protect your ski boots from the devastation caused by running boards. They keep your boots warmer and drier. Extremely easy to put on and off. THe overshoes weigh one pound, and fold flat allowing you to store them anywhere. For the last 4 years, these overshoes have been one of the most important pieces of snowmobiling equipment I have. If you are frustrated with sled skiing because of your hard shell ski boots, you need to buy these. You can thank me later.
