These to caps, also called "Level-Ups" have thickness at the tips and extenders that you can use to help "extend" the length of your toe. Each set comes with two big toe extenders and two smaller toe extenders.

If your second toe is longer than your first toe, you can use the big toe cap to help even out your toes. If your big toe is your longest toe, you could use the second toe cap to even out, or the big toe cap to alleviate pressure.
