I wanted to use them to separate my toes. Don’t work for that
Do not have big gap between big toe and second toe on both foot but need alignment to even pressure. I am a beginner pointe and an older student. Every little tools help. Length is fine but the height can be shorter. For reference I have very thin feet and second toes longest.
These spacers are very small, hence the name narrow, and work well for your smaller toes. I would get another size for between your big toes.
