My Salomon Spikecross winter running shoes have been a staple in my winter running on Colorado Fourteeners for several years now. Over the years they’ve become tighter and tighter due to my aging feet becoming longer and wider with all the miles I’ve put on. Instead of throwing them away, here’s an experiment to heat mold them.
Heat Molding the Salomon Spikecross Video Tutorial
My wife molds her Edea Ice skates frequently. I’ve molded intuition liners, LaSportiva Spantik Liners (hidden feature), and Sole insoles. This is the first time I’ve tried to mold running shoes, but the construction of the toe of the Spikecross is very similar to the Spantik liner, so I assumed it would be acceptable to attempt to heat mold them.
Currently, it seems to have worked, so I’ll give them a shot on a trail run in the mountains here in Utah and get back to you in another video coming soon.

I’ve been wearing the Salomon Spikecross winter running shoes with carbide spikes for several years, but sadly my feet have grown longer and wider with age and miles. I didn’t want to throw them away, so here I’m showing you an experiment, hopefully successful, to heat mold them, similar to how you heat mold Edea figure skates, La Sportiva and Scarpa climbing boots, etc. The Salomon Spikecross is based on the Speedcross family and also includes the Snowcross.
Be warned though, that this might not work for all running shoes, and could cause permanent harm to them or you. Please use common sense and make an intelligent decision.
