My first marathon
These got me through all of the training for my first marathon and through race day.
Normally I’ll get a pain in my knee after around 25km but with these I was pain free on race day.
Also sped up my recovery afterwards!
I couldn’t recommend more!

Excellent compression
Great leg sleeves with excellent compression.
I’ve always struggled with runner’s knee, and these have honestly been one of the most effective solutions I’ve found. I’ll definitely be buying more in the future when needed.

Great leg sleeves
Great leg sleeves - great compression.
Used these to help me back into running with Hamstring tendinopathy & associated knee issues. Helped so much and now generally use them for recovery after bike/runs. Will definitely get more in future when needed.

Supportive without being restrictive
I’ve been using Human Dynamix compression gear consistently for both training and recovery, and the difference has been noticeable. The fit feels supportive without being restrictive, especially on longer runs and harder sessions. …

A lot more comfortable
I’ve been having trouble with my knee for a few weeks, which made it hard to run comfortably during rugby. Yesterday, using the HDX brace, everything went much better and felt a lot more comfortable.

FAQs
KneeMax is designed to give you extra knee support when you need it most.
It helps stabilize the joint during training, sports, or periods of higher physical load, supporting natural movement while reducing discomfort. Many athletes use KneeMax to feel more confident in their movements and more comfortable during and after intense sessions.
They’re suitable for a wide range of sports, including running and jogging, basketball, high-impact jumping sports, football and soccer, tennis and other court sports, cycling and long-distance riding, gym workouts and strength training, CrossFit and high-intensity training, hiking and outdoor activities, volleyball and badminton, and various combat sports.
KneeMax is meant to be used as a supportive aid during activity.
Wear it during workouts, runs, or long periods of physical exertion when your knees need extra stability. It is not required to wear KneeMax all day. Use it when you want added support and comfort, and leave it off when you don’t.
You can wear them for 2 to 6 hours at a time during activity or recovery. They’re designed to be worn throughout your warm-up, training, and cooldown, and can also be worn longer during daily use as long as they feel comfortable. We recommend removing them periodically to allow your skin and circulation to rest.

Ik heb gisteren een marathon gelopen. Op 10km kreeg ik kniepijn en zag het niet goed komen. Op 23 km heb ik besloten om de kousen aan te trekken en het bleek beter en beter te gaan. Ik heb de resterend kilometers de perfecte ondersteuning gekregen en heb de marathon in her 2de deel zonder kniepijn uitgelopen. I love it ❤️❤️

I’ve been using Human Dynamix compression gear consistently for both training and recovery, and the difference has been noticeable. The fit feels supportive without being restrictive, especially on longer runs and harder sessions. I’ve found my legs feel fresher post-run, recovery between sessions feels smoother, and the material stays comfortable even during longer wear. As someone who runs high mileage, I also appreciate that the quality holds up well over time. Highly recommend for runners and athletes wanting reliable compression for both performance and recovery.
I love my knee max compression sleeves! They feel so comfortable and I barely notice they're there while I'm wearing them!
I've also been running faster when I wear them and my legs feel less fatigued after my run.
Best knee sleeves out there!
Zakken niet af. Geven goed steun en je voelt ze niet als je ze draagt.
Werkt beter dan een knie brace. Heb er al meerdere geprobeerd, maar deze werken echt goed. Geen last van mijn knie tijdens het sporten en ook niet de dag erna.
ze rollen op, en doordat ik ze aan heb, gaat mijn huid en vet er overheen wat heel irritant is. ook weer niet niet goed of ze helemaal naar boven in je kiezen moeten of halverwege je bovenbeen? hoog optrekken, zit heel vervelend bij je billen, en halverwege je bovenbeen drukt te veel op je spier...
I used The kneemax if I am running or training for a HYROX! I am 69 year a i loved this kneemax. Very comfortabel en the compression is good. So I recommend the kneemax!
The items arrived on time and were neatly packaged. Both sleeves fit well around my legs, they don’t slip down, and they keep my knees stable. I can now walk for a long time without experiencing pain in my knees or legs.
Hebt goed bij mijn knieletsel (voorste kruisband gescheurd en weer aan het hardlopen d.m.v. conservatieve fysio). Minder pijn/ last tijdens het rennen en sneller herstel na het rennen! Zit goed en zakt niet af
Top product. I suffered from jumper's knee months ago. Today I ran a 5km race for the first time since then. I didn't experience any knee pain; it’s comfortable and stays in place well. The only downside is the long shipping time.
Sleeves zitten prettig en voelt als een echte ondersteuning. Doe Hyrox traingen en mijn knieen krijgen zo wat extra steun. Ga snel een paar bij bestellen!
