## Questions & Answers

**Q: Should I put this upper or under the tight fit leggings?**
A: I've never worn with tight leggings but suggest trying both ways. Sometimes the bands slip a bit and it might be easier to tug it back up if its one the outside. With tight leggings you'll probably get the full benefit (support) worn either way. One trick I've found to help with the slipping (I wear them while on longer walks) it to pull them up initially high on my thigh.

**Q: Do you have a small/ medium knee support by mueller?**
A: Small

**Q: Can this be machine washed?**
A: Recommended product care: hand wash, cold. Air/line dry.

**Q: Do these sleeves contain latex?**
A: no
