Keep Boots & Feet Warmer During Winter With Foil Insulation Sole Inserts

Keep Boots & Feet Warmer During Winter With Foil Insulation Sole Inserts by Ken Jorgustin for Modern Survival Blog

I had a brainstorm on how to keep my feet warmer in my boots or hiking shoes. Foil insulation sole inserts! And it worked!

It dawned on me the other day while working on a project in the garage. My feet get cold after awhile standing on the chilly concrete floor.

It can happen anywhere. Just being outside standing on the frozen ground after awhile. The cold creeps up through the soles and into the bottom of your feet. Even with insulated boots.

TA-DA!! Here’s how to keep your boots and feet warmer…

Do-it-yourself Foil Insulation Sole Inserts

I had a leftover partial roll of “Reflectix”. It’s foil insulation. Aluminum foil sandwiched / bonded to a layer of polyethylene.

I had been using it behind my radiators to reflect heat back into the room that would otherwise go right into the wall behind them. (It works great for that by the way).

So I thought, why not cut some pieces the same shape as the sole inserts in my boots? In theory this would reflect the heat from my feet, back into my feet! And reflect the cold from the ground, back down to the ground where it belongs!

I simply removed the inserts from my Merrell’s and the inserts from my snow boots.
I laid the inserts on top of the foil insulation.
Got out a Sharpie and traced the outline.
Cut them with scissors.
Then insert the new foil cut-outs into the boot.
I replaced the original sole insert on top of the foil insulation cut-outs.

I was concerned that the additional inserts would make the boots too tight fitting. But it worked out okay. I just loosened the laces a bit more than otherwise. No problems.
