THE ULTIMATE EXTREME PRESSURE LUBRICANT WITH POLAR BONDING CAPABILITY. PROVIDES THE LOWEST COEFFICIENT OF FRICTION MEASURABLE ON METAL-TO-METAL WEAR SURFACES Performance Specifications Lubrication / Anti-Wear ASTM D4172: 0.242mm Friction Coefficient: 0.044 Load-Carrying Capacity ASTM 2625 Method B: 750 lb. average last sustained load Corrosion Protection Salt Spray ASTM B117 @ 0.19 mils thickness: >336 hrs. Corrosion Protection Humidity Cabinet ASTM D1748 @ 0.19 mils thickness: >1320 hrs. SpeedX® is an extreme performance lubricant whose additives chemically react with metal surfaces and subsurfaces to reduce wear and provide the lowest coefficient of friction measurable. SpeedX lubricates better than products with PTFE. It gives long-lasting, heat-resistant lubrication, decreases wear and extends the useful life of treated items and parts. Skateboards, roller skates, chains and derailleurs operate smoother, quieter, with greater efficiency and last longer when treated with SpeedX. SpeedX thrives under heavy loads and high temperatures! Other lubricating oils are displaced by moisture and pressure – so their effectiveness is diminished. Even under the best circumstances, other lubricants don't last (comparatively) very long. Not so with SpeedX! SpeedX Polar Bonds with metal and metal alloys and clings tenaciously like a magnet. SpeedX releases the surface tension of moisture, displaces it and maintains its fantastic lubricating capability. The exotic additive package in SpeedX is activated by heat, either external or internal (frictional heating), and causes the surface and subsurface of the metal to be modified. The modified surface becomes both smoother, allowing for the transition to hydrodynamic lubrication more easily, and intrinsically possesses a lower coefficient of friction. SpeedX does not contain any corrosive chlorine or suspended solids such as PTFE, graphite or molybdenum disulfide. The three-dimensional graph below plots Load (x-axis) and Temperature (y-axis) in degrees F against the friction coefficient (z-axis). The friction coefficient is defined as the frictional force (perpendicular to the wear surface) divided by the applied load. The measurements taken in this example range from 2,000 psi to 40,000 psi in load and 75˚ to 300˚F. Friction Coefficient vs Load and Temperature This data is generated by a FALEX Block on Ring instrument. The instrument uses a block that is pushed against a rotating ring. The frictional force is measured as the block tries to move tangentially (sideways) due to friction. The friction coefficient of steel lubricated with light unadditized oil goes from near zero at low loads (parts held apart by an oil film or hydrodynamic conditions) to a very high coefficient of over 0.20 at high loads (full metal-to-metal contact or boundary conditions). Most good quality lubricants (including motor oils) tend to have boundary friction coefficients in the range of 0.15 to 0.18. Increasing Temperature Increasing Temperature Increasing the temperature of the lubricant decreases its viscosity thereby reducing oil film thickness and allowing boundary conditions to occur at lower load pressures. This causes the friction to increase. This is demonstrated on the red CorrosionX graph as the temperature goes from 75˚ to 300˚ F at a constant load of 2,000 psi. Under these conditions, even with a superlative lubricant like CorrosionX, the friction coefficient goes from 0.01 to 0.083. Under the same conditions, SpeedX's friction coefficient goes from 0.01 to only 0.02. Increasing Load The friction coefficient also goes up with increasing load at the low temperature 75˚F (this condition requires a lot of cooling). As load is increased, the lubrication state goes from hydrodynamic to full boundary conditions. The maximum friction coefficient for CorrosionX is 0.15 versus 0.08 for SpeedX. At high temperature, high load conditions, the friction coefficient is 0.14 for CorrosionX, but only 0.03 for SpeedX! This is the lowest coefficient of friction measurable on lubricated (but otherwise uncoated) steel. The industry's best protection vs. rust and corrosion plus ultra-low friction is the formula for SpeedX! Use SpeedX for remarkable lubrication of: Precision instruments and gears Bearings (particularly high speed and/or high load) Bicycle and motorcycle chains Gears Derailleurs Cables Slot cars Any other metal-on-metal applications where eliminating friction and wear is paramount Corrosion Protection and Rust Preventive Coating Due to Polar Bonding, SpeedX causes common metals and metal alloys such as iron, steel, stainless steel, aluminum, copper, brass, bronze, etc. to chemically behave more like noble metals such as gold and platinum. In other words, as long as SpeedX is present on metal, it can't rust or corrode! To learn more about Polar Bonding, please visit our technology page. Minimal Environmental Impact Product The volatile organic content (usually abbreviated as VOC or VOCs) of SpeedX is now ZERO. Compare that to most products in the spray lubricant category, which can be 50% or more VOC (for example, according to their current Safety Data Sheet, WD-40 is 49.5% solvent). That means SpeedX is many times more gentle on you, your equipment and the environment.Shipping Notes

Great for walking all day at work as well
Size: X-Large, Color: (001) Black / Black / White
I walk approximately 10 miles a day at work, in a manufacturing setting. On concrete with steel toe shoes. My feet have been begging me to change from the socks that I have worn for years. I have worn these other name brand socks for probably 10 years. So, change was obviously something I had to be pushed into. I got on Amazon and searched for training socks. I read the description. Glanced at the reviews. I decided to move forward with purchasing these. I could not have been happier. My feet began feeling better immediately. And the priced was very reasonible.

Absolutely Essential for Any Athlete or Gym-Goer!
Size: Large, Color: (035) Steel / White / Black
I recently purchased the Under Armour Unisex-Adult Training Cotton No Show Socks 6 Pack, and I must say, they've become an indispensable part of my workout gear. Here's why these socks are a game-changer:
Comfort Above All: These socks are incredibly comfortable. Made from a blend of cotton and synthetic fibers, they provide just the right amount of cushioning without feeling bulky. Whether I'm running, lifting weights, or doing yoga, my feet feel supported yet free.
No Show, All Go: True to their name, these socks stay perfectly in place without slipping down into my shoes. This is crucial for maintaining a professional look at the gym or during sports activities. No more embarrassing sock peeks or having to constantly adjust them.
Durability: For the price, these socks hold up remarkably well. I've washed them multiple times, and they haven't lost their shape or elasticity. They've survived the rigors of both my workouts and laundry day.
Breathability: The material mix allows for excellent breathability. My feet stay dry and cool, reducing the chances of blisters or discomfort during long sessions.
Pack Value: Getting six pairs in one go is fantastic. It means I always have a fresh pair ready, which is perfect for someone like me who works out frequently.
Fit for All: These socks fit true to size and are designed to be unisex, making them a versatile choice for anyone looking to upgrade their sock game.
If you're in the market for socks that combine comfort, performance, and style, look no further. Under Armour has nailed it with these no-show socks. They've quickly become a staple in my wardrobe, and I find myself reaching for them over any other sock I own. Highly recommended for anyone serious about their fitness routine or just wanting reliable, high-quality socks.
5 out of 5 stars - These socks are a must-have!
