Can I heat fit my own ski boots?

Answer 1

You really don't want to use your own oven. The ovens at the ski shops are designed to hold the liners so they don't get burned. If you can find a way to keep your boot liners from the hot surfaces in the oven then here's what you do next.

Heat the liners at about 300 for 15 minutes. I actually would check the liners every 5 minutes or so. 10 minutes usually does it.

After they are baked, stick them in the shells. Then stand in the boots for about 20 minutes. Buckles buckled and straps strapped tight. You need to stand so your heels are angled into the heel cup of the boot. Usually standing with the toes of the boots on a 1" dowel will give you the proper angle.

After 20 minutes you should be OK.

It's just a lot easier to take them to a shop. They might charge you $20 or so, but it's better to have a bootfitter do it the right way. Also, if they F it up than it's their fault and they have to give you new liners. You screw up and it's gonna come out of your own pocket. Plus, they have the things like bootjacks and other fitting tools.
