Coaches and physical therapists

Coaches and physical therapists tried it first.

Alex Mercer Alex Mercer Coach · Certified Pickleball Coach & Pro Player · Florida Paddle Club, Miami
“The Florida heat makes standard knee braces completely unwearable. This strap is a breath of fresh air. It provides the exact patellar stability my players need for quick transitions without trapping sweat or sliding off mid-rally.”
Brad Miller Brad Miller Coach · Pickleball coach · Lone Star Pickleball Hub, Austin
“I used to wear bulky knee sleeves that trapped heat and slipped down during long drilling sessions. This strap delivers targeted compression exactly where it counts, locks in place, and stays completely cool.”
Dan Wright Dan Wright Coach · Head Pickleball Coach / PPR Certified · Austin Pickle Ranch, Austin
“Drilling everyday takes a massive toll on the knees. I've switched over over a dozen of my students to this strap because it doesn't restrict their lateral movement or speed when rushing the kitchen line.”
Sarah Jennings Sarah Jennings Physical therapist · PT, DPT · Premier Physical Therapy, Scottsdale
“Secure it exactly two fingers below the kneecap before warm-ups. I recommend it to patients looking to offload patellar tendon stress during explosive kitchen line lunges without the bulk of a full brace.”

Much less discomfort after wearing whilst exercising

I've suffered with knee pain for several years now, after several injuries playing sports, and always used the old fashioned "sleeves".
I recently purchased your product and yesterday did a one hour plus session in the gym (cross trainer, treadmill and bike). Woke up this morning with far less pain than usual.

I was skeptical

I was skeptical, tried it and used it for past two weeks walking through Italy! Amazing support 7-10 miles per day even on old cobble stone streets my knee held solid with awesome support and zero pain.

Never thought they would work so well.

I am 61 and pickeball 4 times a week. I had been wearing a sleeve and it help amazingly so thought maybe I should try the second set knee straps so have been wearing two for past month and not once has my knees crunched or felt sore since wearing them like before. Truely amazing! One wee point was that once one strap fell off but was handed in by someone.

Before you order.

Why do most players take the Doubles Pack?

Most pickleball is played as doubles. The Doubles Pack gives you one strap per knee, or one for you and one for your partner. One size fits you both, so there's no size to ask.

Will it fit my knee?

Yes. Second Set is one size: the metal slider and the hook-and-loop set it to your leg, 30–45 cm (12–18 in) around, measured two fingers below the kneecap. Set it once and it stays set. Doesn't fit you? The 60-day guarantee covers it.

Will it fix my knee pain?

Second Set is a support strap, not a medical device, and it doesn't treat injuries. If your knee hurts, see a physical therapist or a doctor.

When do I put it on?

Before your warm-up: two fingers below the kneecap, snug but comfortable. Take it off after the match and let it air dry.

Will it get in the way of my game?

No. It sits under your kneecap, stays slim under shorts, leggings or a skirt, and your knee bends freely.

Which colour should I pick?

Three colours, same strap, same price: Ink (black), Chalk (grey) and Blush (pink). Buying a Doubles or Club pack? Tap Mix colours and pick one per strap.

Can I wear it for tennis or padel too?

Yes. It works for any sport that stops and starts: tennis, padel, running or the gym.

How do I get the 8-week program?

It's free with every strap. The download link is in your order confirmation email, so you can start the same day.

Court at 8pm. Need a fourth?
