She gained inches on her jump…
My daughter plays club and High School Volleyball. I wanted to give her an edge on her verticle jump at the net, and some height on her swing (outside hitter). She was extremely reluctant to try these insoles for some reason, but once she did, it was a HUGE difference. She gained INCHES on her jump and LOVES how these allow her to play longer without getting tired.

Legit game changer…
We bought my son the Gold pro-level VKs for Christmas. He had come off of a summer injury and it was his high school basketball senior season so we wanted to give him a boost, and add protection! These inserts were and are a game-changer in his performance! If you are on the fence about purchasing Vk’s, do not be! They are 1000% legit!!!!

My son loves the insoles…
He has really flat feet so they’re helping him a lot. His explosiveness is awesome! He can move up and down the basketball court much better than before.

Product was received very quickly…
My daughter has been using your product for 6 years and is very happy about it. She tried going on without it for about half a season and that didn’t last. She said it makes her feel a lot quicker and lighter on her feet. Thanks for making a product where athletes can take advantage of having that little edge over the competition.
