So our equation doesn't strictly align with the accepted definition of speed in the world of academic physics, but for the purpose of grip socks, it's what we use at Apex to drive our advancement in elite performance.
The Equation
We've simplified this extensively, but the idea remains:
Speed = Initial acceleration & short directional change
Power = Applied force from body, to sock, to boot
Grip = Limits or enhances that applied force
Which looks like Speed = Power x (Grip)
The Science
Okay, so listen up class as we get techy. Your 'Speed' score is based on:
Force Applied x Grip Available
Your 'Power' score is based on the biomechanical force (Mass x Acceleration) applied when pushing off the ground. So, 80kg x 2 m/s (2m in 1 second from standing start) = 160.
The 'Grip' score is based on how well the sock base fits your foot, combined with the effectiveness of the grip pads to limit slippage or enhance acceleration.
The Maths
Time for some quick maths. Let's break it down in this example:
Standard White Crew Socks
- Your Power score equals 160
- Your Grip score equals 1
- Your Speed score equals 160
You get an even speed score as the white crew sock fits okay, but is not enhanced with grip pads, or an exoskeleton. The deciding grip score remains at 1.
Standard Grip Socks
- Your Power score equals 160
- Your Grip score equals 1.25
- Your Speed score equals 200
You get a good speed score as normal grip socks have grip pads, but don't fit in all weather conditions. You have better grip, but limited power application.
Apex PRO 2.0 Grip Socks
- Your Power score equals 160
- Your Grip score equals 1.5
- Your Speed score equals 240
You get a great speed score as you have a great fit, grip pads, and the Apex ExoFrame. In this case you can apply more power with better grip.
The Grip
Grip is the decider.
The quality of the stability and grip you get with an elite football sock defines your ability to apply speed.
We may only be talking about that 5-10 millisecond advantage, but every 1% counts when it's the difference between winning and losing your individual
battles on that pitch.
We're iterating and perfecting how we gauge grip performance everyday. This is just the start as we chase down even more ways to reduce slippage, eliminate wasted energy, and double down on power transfer.
