Foot structure.
It's more than just toe lengths, but the quickest way to guess at your foot structure type is to look at your toes.

If you have a second toe that is longer than your first toe, and/or if your toes are very long - might be Irish or Greek (or "Royal") foot.

If your second toe is shorter than your first toe, and/or if your toes are very short - might be Roman foot.

There are more distinctions than that (metatarsal proportions, toe break angle, etc.) but that's the short cut definition.
