Lock In.
Game, Set, Match.
Every court shoe ships with a thin, slippery insole. On the split-step before the return, the sprint to net, and the hard stop on a baseline scramble, a sliding foot costs you the point. Blumaka NonSlip locks your foot to the footbed, so nothing gets between you and the win.
$60· Outlasts 3 to 4 pairs of shoes. About 6 cents a mile.
Only pay if you perform.
We offer free shipping on all orders in the United States. We will ship in 24 hours after receiving your order excluding weekends and major holidays.
By default, all orders will ship USPS. Expedited shipping is also available. However, we'd like for you consider using USPS. USPS is required to visit every household in the United States six days a week. So since they're already going to your house, we'd like them to drop off your insoles at the same time. UPS and FedEx are luxury choices as they make a special trip to your house. Any package shipped by those carriers adds to the carbon footprint and therefore, additional charges will apply.
For more details or other questions, please see our FAQ.
We are proud to offer a 90 Day Performance Guarantee, which means that if you're not completely thrilled by your Blumaka insoles, you have a full 90 days after receiving your item to request a return and receive a full refund even after you've worn them.

- Fabric top covers let your foot slide inside the shoe.
- A sliding foot bleeds off the speed and control you worked for.
- Thin liners flatten out long before a three-set battle is over.

Pull the stock insole. Drop it in.
Swap the stock insole for the NonSlip Max Cushion in under two minutes. Same shoe, same fit, just a grip layer underneath that keeps your foot from sliding on every split-step, sprint, and cut. Three arch heights, Low, Medium and High, so it matches your foot instead of a generic mold.
Easy returns. Fast, no-hassle refunds.
What keeps your foot locked in.
NonSlip technology
A high-friction top layer locks your foot to the footbed through every split-step, sprint and hard stop, so no push-off leaks away as a micro-slide inside the shoe.
Max Cushion, engineered
85% recycled ETPU foam adds extra shock absorption and energy return, built for players who want more cushion under a long tournament day.
Built for the grind
Outlasts three to four pairs of shoes and comes backed by a 1,000-mile cushioning guarantee, the same setup from the first match to the last of a long tournament.
Built to last 1,000 miles. Outlasts 3 to 4 pairs of shoes.
Every point is decided in one step.
The split-step before the return. The sprint from the baseline to the net. The last push to reset your feet before the next ball. That's where a loose insole costs you a fraction of grip, and on a tennis court a fraction is the whole point. NonSlip holds your foot in place so every ounce of that push goes into the court, not into your shoe.
Free shipping. On every order.
Real athletes. Real results.
From the MLB to the pitch to the pickleball court, the same NonSlip platform.
“Quick changes of direction are a huge part of tennis. Blumaka keeps my footing secure so I'm not slipping inside my shoes, with great cushioning through long matches, and even in humid conditions they stay locked in place.”
“My foot now feels glued to my shoe.”
“I feel like I'm walking on clouds.”
“It felt like my foot was locked in place.”
“A game-changing product… I won't play without them.”
“Blumaka insoles completely changed my game. They keep me comfortable in my cleats and give me the grip I need to cut and turn without slipping.”
Three levels of arch support.
Improve your alignment, manage pronation and supination, and keep even pressure across a stride you can rely on.
Low
For low or "normal" arches, promotes a natural gait and biomechanics through every step on the court.
Medium
For average arches, balances support and comfort, and helps with pain relief and plantar fasciitis.
High
For high arches, extra support and cushioning to reduce strain and help relieve plantar fasciitis.
Easy returns. Fast, no-hassle refunds.
Why athletes choose NonSlip.
NonSlip
Straight answers.
Which profile fits my footwear? +
Low Profile is built for shoes where space is limited, which usually means soccer and lacrosse cleats, golf shoes, track spikes, rugby boots and racing flats. Max Cushion is built for footwear with more room, which usually means basketball, tennis, football, pickleball, volleyball, baseball, training and running shoes. If the shoe already feels snug, choose Low Profile.
Which arch option should I choose? +
Blumaka NonSlip insoles come in three arch support options: Low for low or neutral arches, Medium for average arch heights, and High for high arches. If you are between two, the insole quiz will walk you through it.
How do I choose my size? +
Sizes are listed as men's and women's ranges, for example Men's 9-9.5 | Women's 10-10.5. Choose the range that contains the shoe size you normally buy. Men's sizes continue on their own from 13 up to 17.5.
Do I remove the insole that came with my shoe? +
Yes. Take the factory insole out of the shoe first, then set the Blumaka insole in its place. The same pair can move between any shoes it fits, so one pair can cover a rotation.
How do I clean and care for them? +
Remove the insoles from your shoes and hand wash them with mild soap and water. Let them air dry completely before putting them back in.
How long does a pair last? +
Blumaka insoles are made with a durable ETPU foam, which is why we offer a 1,000 mile cushioning guarantee. Most running shoes lose their cushioning long before 1,000 miles, so you can expect your Blumaka insoles to outlast three to four pairs of shoes.
What does the 1,000 mile guarantee cover? +
The 1,000 mile figure is a cushioning guarantee. It covers how the foam holds its cushioning over distance, and it is not a wear or tread guarantee. Returns and refunds are handled separately under the 90 Day Performance Guarantee below.
What is your shipping policy? +
We offer free shipping on all orders in the United States. We will ship in 24 hours after receiving your order excluding weekends and major holidays.
What is your return and refund policy? +
We are proud to offer a 90 Day Performance Guarantee, which means that if you're not completely thrilled by your Blumaka insoles, you have a full 90 days after receiving your item to request a return and receive a full refund even after you've worn them. However, we do not accept insoles that have been trimmed. To start a return, contact us at help@blumaka.com.
Are your mailers recyclable? +
Yes, our mailers are recyclable. We chose a 100% recycled brown paper envelope as our mailer because nearly every recycling center around the world can accept paper and recycle it.
Can I send my Blumaka insoles to you to recycle when I am done? +
Not yet, but we are working to make this possible. Sign up for our email list and we will email you when this is available.
What should I do with the old insoles I take out of my shoes? +
We recommend donating insoles that are still in good condition, or you can turn them into a fun art project!
