After three decades working with high-level athletes, very few products still get JC’s attention.
JC is a managing partner at Fast Performance, where he helps run the business, coaches athletes, supports education, and evaluates new performance technology. Over 30 years in the space, he has seen just about every trend, gadget, and “breakthrough” come and go. Most never make it past the first conversation.
His filter is simple. Show the data. Then prove it in real use.
Data First. Always.
When evaluating any performance product, JC’s first request is third-party research. White papers. Independent testing. Not marketing decks or testimonials. If a product cannot stand up to objective scrutiny, it does not go anywhere near his athletes.
The second step is personal testing. If it does not work for him, it does not get passed along. Most products fail one of those two filters.
Blumaka stood out because it passed both.
The Simplest Problems Are Often the Biggest
Coming from a ski racing background, JC has always understood the importance of foot-to-ground contact. In skiing, power transfer starts at the footbed. Any movement inside the boot costs speed and control.
When he looked at athletes in cleats, the issue was obvious. Most feet were sliding inside the shoe. That internal movement wastes force before it ever reaches the ground.
Blumaka addressed that problem in a simple way. Reduce internal slippage. Improve contact. Let athletes actually use the force they are already producing.
No complicated mechanics. Just better connection.
Why Foot Stability Matters
Performance does not start at the hips or the shoulders. It starts at the ground. If the foot is unstable, force leaks out before it can be applied.
Stabilize the foot, and everything improves. Ground reaction force increases. Movement becomes more efficient. Reaction times sharpen. For many athletes, this is one of the easiest and most overlooked ways to improve performance.
Small gains here matter because margins are small everywhere else.
Tested Against Custom Orthotics
Before fully buying in, JC tested Blumaka himself. In cycling shoes, he compared them directly against $220 custom orthotics. The result surprised him.
Blumaka produced equal or better power output.
That was not a marginal win. That was proof that a simpler solution could compete with highly customized, expensive alternatives. More importantly, athletes noticed immediately.
When athletes put them on and say, “I can feel the difference,” that feedback carries weight.
Performance Is Not Just for Pros
JC is quick to point out that Blumaka is not just for elite athletes. He uses them himself. At 57, he hikes, skis, trains, and lives an active lifestyle. Better footing matters at every age and ability level.
Foot health is foundational. Your feet support your entire body all day, not just during training sessions. Cushioning and support play a direct role in recovery, longevity, and overall movement quality.
When feet feel better, everything up the chain benefits.
The 23-Hour Rule
When asked what separates professional athletes from those chasing the next level, JC does not talk about talent. He talks about focus and discipline.
Training might take one hour a day. The other 23 hours decide everything. Sleep, nutrition, stress, recovery, and daily habits determine who progresses and who stalls.
The athletes who make it are willing to shut off the noise and make small sacrifices consistently. Earlier nights. Better choices. Fewer shortcuts.
Built on Fundamentals
Blumaka earned its place at Fast Performance because it solved a fundamental problem with data, simplicity, and real-world results.
No hype. No shortcuts. Just better contact with the ground.
And at the highest levels of sport, that is where performance begins.
