Unfortunately, the ones I’m a fan of have been discontinued. It was the Enduro-Sole by Columbia. I lived near a Columbia clearance store when they got axed, and they had a TON of them for super cheap, so I stocked up.

…and I’m almost out. Q_Q

What made them good is that they’re made of a rubbery material that gets soft when it’s super hot, so the first thing you’d do when you crack a new pair open is put them in the oven and bake them at like 250* for a few minutes. Take them out, quickly put them in your shoes, step in, and just walk a bit until they cool.

It was hot enough to be uncomfortable, but not so much that you’d actually get burned. Kinda like molding a mouth guard from boiling water.

Anyway, once it conformed to your feet and then cooled, that shape became permanent, so even with a brand new stiff-ass pair of shoes, you pop those insoles in and it’d feel like they’ve been broken in for years.

There’s probably something else on the market that works the same way, but I haven’t actually searched, since I’ve never needed to; but the Columbia ones at least are SO comfortable!
