A cleaner drive phase
Out of the blocks, every degree of pelvic instability is speed you never get back. Support keeps the drive line honest.
Track / Sprinting / Hurdling
Compression Shorts Built For The Track
Sprinting is the most honest test of a stable pelvis there is. The Lock's patented 'D Band' supports the pelvic floor so your drive phase, your turnover, and your trail leg all work against something solid.
Why It Works
What track / sprinting / hurdling demands of your core
The patented "D Band" supports the pelvic floor and locks the core — the foundation every other movement is built on.
Turnover at top end
High-frequency mechanics need a still pelvis. Sprinters report their form staying together through the last twenty metres.
Hurdle mechanics
Lead-leg snap and trail-leg clearance are hip-driven. A supported core keeps the pelvis square over the barrier.
Support at speed
The Lock holds the anatomy securely at full sprint — no shifting, no readjusting on the line.
In Their Words
"As an ex-Olympic hurdler, I'm amazed that a pair of running shorts could actually enhance my performance. After only 2 weeks the small aches and pains that are just part of being an athlete have miraculously disappeared. The Lock is truly a performance-enhancing piece of gear that every athlete should add to their arsenal."

The Technology
Patented, not just tight
The same platform every track / sprinting / hurdling athlete on this page is wearing. You only need to wear The Lock once to feel the difference that separates it from any comparable short on the market.
The D Band
A patented band that supports the pelvic floor and holds the anatomy safely against the pubic symphysis — stability where compression alone does nothing.
Differentiated fabrication
The panels distinguish between muscle groups, so support lands where it's needed and freedom of movement stays where it matters.
Active Cotton
100% cotton engineered to move moisture away from the skin, resist odour, and stay soft without going heavy, sticky, or cold.
More Athletes
Same platform. Different arenas.
"Every stride translates more force into the ground. I stopped feeling my hips fatigue at mile 18. The Lock keeps my core and pelvic floor stable the whole way — that's the difference between finishing strong and just finishing."

"The Lock clothing made my training a lot more comfortable. I really noticed a difference when I went back to normal gear. It even corrected my form while running — forcing me into a more suitable stance. The bra was so well-fitted I was almost unable to tell I was wearing it. Everything is really great."

"I've only ever worn the big synthetic brands — they get baggy and smelly. When I tried The Lock I was blown away at how dry it stayed even after a long workout or a 90-minute hot yoga class. The breathable material allowed my legs to have better range of motion, even late in the workout. The anatomical support is why it's patented."
