I’m in between sizes for shoes I really like (Nike Pegasus 35s). M size 10 feels too big and F size 11 (bigger than M 9.5 for Nike) is a little too tight. I took the insoles out from the smaller pair and they feel great in terms of space, and I feel like there’s room for thinner insoles than Nike original. Any recommendations on what I could try?

Most of my other running shoes are M 9.5 or F 11.
