What's the best way to prevent that? I took out the paper after searching last night and thinking about buying silica gels for future shoes. I don't mind it yellowing but I don't want to have it yellowed already the first day I wear it.
I haven't worn my yet; waiting for warmer weather but my sole seems to be getting dirty already or maybe I'm wrong. Anyone if these soles will yellow even if it's not been worn yet?
