How much room do you allow for your toes in shoes? I mean the length from the longest toe to the end of the shoe...

Seems like I have heard more than once that about a thumb's width space from the end of the toe to the end of the shoe. You can tell this by: 1) pressing on the toe box while wearing the shoe, or b) taking the insole out and stand out it, thumb width length to the end of the insole.

I know ultimately the shoe should feel comfortable etc. I have had such an ongoing thing with my feet that I don't think I know what that is suppose to feel like anymore.

I'm close to finding bike shoes "I think" work but I was just curious if TE bike folks followed this spacing, or not. I know it's something that I think runner's follow for their shoes.

Just trying to make a decision if the shoe fits well enough to buy or not. Thx!
