VKTRY Gold for Non-Cleated Shoes - Carbon Fiber Performance Insoles - Customized Athletic Inserts for Sports Basketball Volleyball Running & More | Shock Absorption US M5.5-6, W7.5-8, 121-170lbs

This is all my 17 year old wanted for Christmas. He plays volleyball and cant wait to get out on the court and put these to use. He says they are comfortable, perfect fit (size 13 mens) and the quality is unmatched. They are perfect thickness to be able to remove the inside soles of his volleyball shoes and slide right in. They do not smell (so far) but he will be keeped good care of them. He has flat feet normally and says that he feels supported in is arch more than he has every felt. You get what you pay for and the quality and function of these is money well spent. 10/10!!!

Very good stability and comfort once broken in.

VERY GOOD WHEN I PUT THE INSOLES IN IT FITS EASILY INTO MY SHOE!!! PERFORMANCE:I FELT A BIT OF LIKE ENERGY RETURN I JUMPED EXACTLY 0.7 INCHES HIGHER IMMEDIATELY BUT I DON'T KNOW IF IT WORKS FOR OTHERS! SHOCK ABSORPTION:WOWWWW I'M IMPRESSED, WHEN I JUMP I DON'T FEEL MUCH PRESSURE IN MY KNEES AND ANKLES Price:VERY EXPENSIVE I THINK U SHOULD BUY WHEN IT HAS A BIG SALE AS IT IS VERY EXPENSIVE

After suddenly receiving dozens of targeted ads on social media touting the almost magical abilities of the VKTRY carbon fiber insole to improve a vertical jump for sports such as basketball and volleyball, I thought I would try them. It was a minor disaster. The carbon fiber insole did not produce the "explosiveness" as advertised all over the website and packaging. Instead, the lack of cushioning and hardness led to tendonitis after just an hour of use. I was *not* going to write a review initially, but after contacting the sales team to ask how to return the product under the advertised return warranty, I was subjected to a multi-email gaslighting insisting there was nothing wrong with the product. The core argument was that the product works, and if I developed tendonitis, I must have used it incorrectly, or purchased the wrong ones. Now, I will say, I am a fairly thorough person in life. Despite looking for details on how to select the correct insole for my sports of choice, I saw nothing specifying that some had better cushioning for jumping. Also, nothing in the ads or the website or the product packaging discussed any contact with a support staff member pre-purchase to determine the best product fit. Rather than spend 30 minutes drafting various emails trying to shift blame on to each individual customer simply seeking to return an item that caused an injury, the company should fix its product, improve its website, use less generic marketing verbiage and be more precise, and redesign its social media campaign.

They fit better in one of my shoes, as they will raise the back of your heal in some shoes. So far I like the firmness and stability. Good quality, good arch support, and thickness. I’m coming back from a 5th metatarsal fracture and my foot feels much better with them in!

Fit into my volleyball shoes well, sizing was spot on and it doesn’t crowd the toe box or push the foot too high in the shoe

Didn’t have time to break these insoles in properly and they still performed amazing! Can’t wait until they are at their full potential!

Not for me, uncomfortable but did provide some spring in the step
