Reviews

I’m a postal worker, lots

"I’m a postal worker, lots of bending and lifting. The KT Flex supports as well as a full brace…but worry free! No slipping or pinching or getting twisted with clothing. The adhesive used is perfect and 100% waterproof. My knees feel very stable and the comfort level is wonderful, I forget I even have the tape on. The ordering process was easy and all items delivered within a week. It’s difficult to find better service than that! Lifelong customer now!"

Q&A

If I am using the flex along with a full knee application, what application steps do I use? Does the flex get applied first or the full knee application? Is there any part of the full knee application that is left out if using the flex? Thanks.
Hello Nikki! Happy to help here - technically you can do it in whichever order you prefer, but we have typically found that both parts last longest when the tape is applied to the full knee application (I would do the full thing) prior to applying the KT Flex. When taping the knee, just try your best to keep the tape as narrow around the knee/kneecap as possible so it can essentially fit between the two KT Flex strips. Additionally, it helpful to apply KT Flex before going to bed so you are not putting pressure on the structure via bending the joint until it is fully adhered to the skin. I hope this helps!
Does this have metal in it? Wondering, as I have to go through a metal detector to go into work daily.
Hi Tylar! No, this product does not contain ANY metal, so you are free to use it and enjoy the knee stability! Thanks for reaching out.
Can you us KT Flex in combination with the Original KT Tape "Full Knee Support" method of taping? If so would you recommend using the Flex 1st and then using the original over the top? I am going to be competing in a jiu jitsu tournament and would like to avoid using knee sleeves. Thanks!
Hi Lora! Yes! You can absolutely use these 2 products together. In fact, you can use KT Flex alongside any of our tape products. When you apply these two products, it should not matter which one you apply first, as long as you take care not to overlap the strips of tape. This will encourage both products remain on your skin longer. Be sure to apply these products to clean and dry skin and give it a few hours to adhere before working out or getting it wet. I would recommend applying the tape well before your jiu jitsu tournament! If you notice the Original KT Tape have trouble adhering, I would upgrade to our KT Tape Pro. It is made of synthetic performance fabric in order to withstand moisture and sweat better than our Original Cotton KT Tape product, making it better for use within sports! You can find it here: https://www.kttape.com/kt-taper-protm#image Good luck in your tournament!
If I have inside knee pain can you use the tape with support on inside and flat tape on outside knee
Hello Colleen, Thank you for submitting a great question. We do not recommend using KT Flex any way than it is advertised, but I do believe that using it as it may still relieve some pain on the inner knee. Another suggestion I have is using our KT Tape Pro product to tape your inner knee area to target the pain. You can find the product here: https://www.kttape.com/kt-taper-protm#image and the instructions on how to apply it to the inner knee area here: https://www.kttape.com/how-to-apply-kt-tape/kt-tape-inner-knee/ Happy taping!
How many come in a pack?
Hi! In the KT Flex package, it comes with a total of 8 strips of tape, 4 with the structure in it and 4 without. This is equal to 4 uses of KT Flex, as you use 1 structured strip and 1 unstructured strip on your knee. If you would like to watch an instructional video, you can view it here: https://www.kttape.com/how-to-apply-kt-tape/kt-tape-kt-flex/
