I bought these for my 10 year old daughter who is very passionate about basketball. She constantly has a ball in her hands she’s twirling, dribbling or shooting. I saw them using these goggles at practice a few weeks ago and figured I’d check Amazon to see if I could find a pair. I was pleasantly surprised at the price and the quality. There is nothing I can complain about at all.The lower visual field is blocked, but they can still see everything else perfectly. My daughter spends at least 10 minutes a day just walking and running dribbling with these on. It’s already made a difference in her ball handling. She was really clumsy at first with the ball, but now she’s learning to dribble without visual cues and only by feel and anticipation. As far as the fit, I’m really glad it’s a strap, rather than traditional glasses. The strap is adjustable and very stretchy. We have no problems with them sliding off or being uncomfortable in any way. The goggle portion is semi flexible, so it’s great for players of all ages. They fit my daughter, husband and I all well.Overall, everything about them is perfect. I couldn’t have asked for more. For the price I wish I would’ve ordered a few more to have laying around to give out the people.
