put on the whole kit (the ear pieces and the strap) and they worked great! The were easy to slide onto his glasses
These eyewear straps are a life save for my little 5 year old soccer player.  My kiddo has only has his glasses for about the last 5 months, and immediately we noticed that playing soccer with them on was going to be a challenge: his glasses were constantly slipping and he was always having to readjust them.  Doesn't exactly make for a very convenient time when you're trying to concentrate on defending your team's goal.  I ordered these silicone straps, put on the whole kit (the ear pieces and the strap) and they worked great!  The were easy to slide onto his glasses, and they kept them in place.  I keep the ear piece part on his glasses at all times now, because they really help his glasses fit comfortably.  I don't even use the strap part anymore when he plays soccer, I find that moving up the ear pieces to be a little tighter keeps his glass in place just fine.  My husband even stole one set of the ear pieces for his own glasses - they fit his glasses perfect and he loves the way they keep in glasses in place even when he's sweating in the hot southern California sun.
