I run with kinvara 6. The insoles are worn out, and starting to tear, so I took both of them out. Has anyone ever run with road shoes without those insoles inside? Is there any reason not to run like that taking in mind that I don’t care about less cushioning.
It's no problem with most shoes. I run without insoles in most of my running shoes, as well as my cross country ski boots, to give myself more volume in the forefoot.
My feet are wide mainly due to bunions (that don't hurt) that might have developed due to a many tens of thousands of miles of running in shoes that just a bit too tight, until I wised up maybe a decade ago.
I take the soles out of all of my shoes. The little bit of cushion ring is worthless, and I like having the extra room for my toes.
If the insole comes out of a running shoe then it’s definitwly optional. Don’t even worry about it.
Most of the time, I like the way my arches feel with the insole. The touch more support feels better.
But aside from that I still have pairs without, and I run in them without issue.
