## Questions & Answers

**Q: Does this come with the tech strap?**
A: Our Winged Editions do not come with tech straps as the wings will hold the heel section up on the heel. The tech straps are designed to be worn with our Retro versions.

**Q: why are these sizing so small? how do i buy 10.5 using this site?**
A: They're meant to have only a small amount of sandal around your foot, I recommend printing out their sizer and measuring against it. Definitely would have ordered the correct pair the first time if I had done so myself.

**Q: I am woman with 81/2 shoes size. what size will i need to buy with luna? i a little confused. thank you.**
A: I agree that this can be confusing.  I am a woman and have found that my shoe size 7 is true to size for the luna sandal. I tried the 7 and the 7 1/2 women's sandals and the 7 1/2 was too big.    If you are unsure I would suggest going 1/2 size larger rather than smaller.   Be sure not to get confused by the sometimes simultaneous men's sizing.   I think my women's 7 was also a labeled as men's 5?

**Q: I’m a size 6 in women, I see I’ll have to size down but that’s not available. Would you recommend purchasing the size 6?**
A: So…with Luna’s, you really do want to get the proper size. Too small and your toes are over exposed; to large and you’ll undoubtedly catch the excess material in stride and the sandal will fold under foot. I speak from experience - experimenting with Luna’s since 2010. Go to their site directly, get the right size and enjoy the journey of finding your perfect Luna. It’ll likely not be found on the first attempt.
