The Pitcher

Built to keep him throwing gas.

TJ Shook, a right-handed pitcher in the Colorado Rockies organization. His first three years in pro ball went into chasing velocity and cleaning up his mechanics, the grind that decides who gets more innings and faster promotions. That demand for every extra mph is why NonSlip insoles keep his back foot locked to the footbed through the drive phase, so no leg drive is lost to a slip inside the cleat.

The Fit

Pull the stock insole. Drop it in.

TJ swaps the stock insole for NonSlip insoles in under two minutes, in both his game and practice cleats. Same cleat, same feel underfoot, just a grip layer that locks his foot to the footbed so no push-off gets lost between the rubber and release. Available in the Max Cushion and Low Profile builds, with three arch heights to match his fit.

Only pay if you perform.

In His Words
My average velocity jumped from 91 to 93 mph.

Ever since I started using the Blumaka insoles, there's been a noticeable increase in velocity. I was sitting 93–95 in most of my outings, and even touched 97 and 98 mph in one outing. That kind of confidence will change careers. I felt like the most explosive athlete on the field, and I could actually feel the ground under my feet.

Straight answers.

How do NonSlip insoles help on the mound? +

A high-friction top layer locks your foot to the footbed so the drive off the rubber doesn't cost you a fraction of a mph to slide, paired with 85% recycled ETPU foam for extra cushioning and energy return. It's the same setup TJ wears every outing.

Will NonSlip fit my baseball cleats? +

Yes. It replaces the thin insole your cleat ships with and comes in three arch heights, so it drops into most molded and metal-spike cleats and turf shoes. TJ wears the Max Cushion profile in his game cleats and the Low Profile in his practice cleats.

Which insole should I choose? +

For everyday performance, grip, and cushioning, the Max Cushion profile covers most athletes. It's TJ's go-to for game day. Three arch heights either way, use Find my fit to match yours.

Can an insole really make a difference? +

It's tested, not claimed. In independent biomechanical testing, 90% of athletes ran faster and 80% were more stable. The NonSlip grip layer is built to keep every ounce of drive-phase power from leaking away inside the cleat.

How long do they last? +

NonSlip insoles are backed by a 1,000-mile cushioning guarantee and outlasts three to four pairs of cleats. If the cushioning gives out before then, we'll make it right.

What about shipping and returns? +

Free shipping on every order in the United States, shipped within 24 hours (excluding weekends and holidays). Backed by a 90-day performance guarantee: if you're not completely thrilled, return them within 90 days for a full refund, even after wearing them. Start a return at help@blumaka.com.
