I have purchased Asics DS Trainer size 11 (UK). Usually I wear sports shoes of size 10 UK. But after reading reviews that this model runs 0.5 size shorter, i purchased 1 size larger. Now my dilemma is that length wise I am having a gap of 1 inch between toe and shoe edge. But width wise, the shoe fits fine.
1) Is running affected if I run in loose shoes which has 1 inch gap between shoe and toe/heel?
2) If I return this and get size 10, will the width also decrease? If yes, by how much?
The typical recommendation is a thumb-nail width between the longest toe and the front of the shoe. Make sure you are standing when you check, since your feet spread some when you put weight on them. A full size is 1/3 of an inch. So going to a 10 should still make a good fit, particularly since that is would you normally wear. There would be some change in width but it would be minimal. Did you get these via mail-order? It's always best to try them on before buying, if it's a brand/style you have no experience with.
1. Depends on whether and how much your foot moves in the shoe when you run.
2. Some difference, probably minimal. couldn't find a number.
You've already discovered that your feet swell when you run, thus the need to go for a size that is a bit bigger than your normal everyday shoes. But how much bigger (the length between your longest toe and the inside front of the shoe) is very specific to you. And some people have wider feet that others. As lenzlaw mentioned, the guideline is a thumb press from your longest toe... You don't want a shoe that fits too loose - that can lead to blisters and just generally being uncomfortable after a few miles. The shoe has to be loose enough that you can easily wiggle your toes, but tight enough that your foot doesn't move around in it. And with that explaination you can see why shoe fits are a very personal thing...!
(what do I know...? I'm just getting old...)
Guys, I got a smaller size shoe but i think it is too tight for me. See the image below. Althought the length is fine but the height is too small since my toe is pushing against the upper mesh. Why is this happening? WIll the shoe expand or should I return the shoe?
