Ski Instructor Approved

I’ve been a ski instructor for 51 years now and at the age of 69 put in 83 days this season. Was using a Don joy knee brace for many years and was skeptical about using the Stoko Summit K1. Well I don’t use the Don Joy anymore. The Stoko gives these old legs new life, knee, hip and thigh support keeps me out teaching at least 6 hours a day. Just bought my second pair so I can swap out between washes. Just wish they would partner with PSIA & NSP for professional discounts like many other companies in the industry.

Thanks so much for sharing your experience! We are stoked to hear you are feeling the benefits of Supportive Apparel. We do have some partnership opportunities, you can check them out and apply at this page here:

An Exceptional Product

Male, mid 60s, very active and in shape.

I had been experiencing some knee pain while skiing as well as during core/cardio/strength workouts. I have an old ACL graft on one knee and no injuries other than life on the other. I bought the K1 Summit and experienced immediate pain reduction and stability confidence on the first wear. I have yet to wear it skiing but squats, lunges, step ups etc are all radically better for me. I can't recommend more strongly for someone in a similar position to me. Despite some reviews indicating difficulties putting it on its very quick and straight forward. I did have a seam open just a bit and the company immediately and without question replaced the product. I do find the Boa dials a bit uncomfortable during crunches but that is a small issue relative to the huge benefits I am seeing with using it.

No Problems in Powder

I skied deep powder in my new K1s for several days.
No knee pain whatsoever! They are great!
Should keep me on the slopes into my 80s

My knees thank you

I have been a downhill skier my whole life and have suffered from knee pain from skiing for decades. I have tried all kinds of braces in the past that haven't made much of a difference. I decided to try the K1 at the start of this season. It has been absolutely astounding the difference I have experienced. No knee pain on any of my trips this year for the first time! Thank you for your fine work in developing this innovation.

This is what it's all about! Getting everyone back to what they love doing without being held back by injuries, aches or pains. Look forward to hearing what you get up to in your Supportive Apparel on the off-season.

Good, but could be better

Age 54, Meniscus knee issues, long time snowboarder

Great concept and offers great support, but will not lock out for over extension. Product definitely works, but would be great if it could support the leg much much tighter (kind of like pulling on a Chinese finger pulling thing from when you were a kid) to restrict bending which in turn would offer more support especially on real bumpy terrain or jumps. It would also be great if they could incorporate traditional side of knee supports as well as soft lock outs built into the material like slip on neoprene knee braces (maybe a version 2 Stoko!).

All in all its a great concept and does offer support, but I will be looking/ waiting for the version 2 from Stoko

Thanks so much for sharing your thoughts Will! You are right, the K1s do not offer support for hyperextension as they allow for a free range of motion within flexion and extension movements. We appreciate your feedback and will be sure to share it with our team as we continue to develop Supportive Apparel.

Still have Questions?

Stoko accepts returns & exchanges within 60 days of the purchase date. 

We encourage you to put your Supportive Apparel to the test before deciding to return. Move in them, get sweaty, and give them all you got. There is a short break-in period with your Supportive Tights. This means it will take a bit of time before your tights begin to regulate and feel comfortable on your body. They can be a total pain at first and challenging to get used to, Supportive Apparel is very different than any other tights or braces you’ve tried.

All Stoko products provide the same medical-grade bracing support, leveraging our Stoko Support System technology. It is really up to your personal preference what style would suit you the best!

All-Purpose: Both the Supportive Tight and K1 Flux are engineered to deliver support in a variety of activities and is our most recommended product for all-around use. From everyday activity to court sports to golf, the K1 Flux and Supportive Tight can do it all while also keeping you cool with knitted ventilation.

Ski & Snow: K1 Summit is engineered to deliver support and warmth. It was designed for snow sports, such as skiing, snowboarding, and cross-country skiing.

Run & Hike: K1 Tempo is engineered to deliver support and keep you cool in warm environments, such as: running, hiking, and training.  

Similar to other traditional/medical grade knee braces, the Supportive Tight provides support and stability to the body in compromised knee positions; however, the Supportive Tight achieves these outcomes through different means. The Supportive Tight relies on tension throughout the Stoko Support System to generate support, which is made up of cables that are integrated into the tights. The result is support that moves with your body and doesn’t compromise on comfort, aesthetics, or support.
