I mean like the picture

the thongs I wear under my leggings for sport, work and lounging are 100% of the same fabric, but never rubber or plastic strips. I can wear this thongs for 10 hours straight and nothing pinches or feels strange.

I’ve never used a thong with rubber or plastic strips. It looks good but I don’t know if it’s gonna feel uncomfortable.

When I say sport I mean running, yoga and pilates involving lots of stretching

My balls always fall out the sides

I thought this was an australian post, but as a total shock it actually was the other kind of thong. IM FLOORED

There is no other, those are called sandals.

If you’re wearing them at the gym, under leggings or shorts, I don’t know why you would switch from a known good solution to something that might be worse.

Aren’t the clear strap thongs meant for wearing with like a strappy dress that shows hips?

They're a subset of sandals where a thin bit of material gets wedged in your toe crack.

Try men's thongs. They take your balls into account.
