CU4TRO will do more than just challenge the expectations of premium footwear. We are going to completely reframe your thoughts on footwear comfort. Sacrificing comfort for style ends here.
A PROPRIETORY TRI-BLEND OF EVA + RUBBER + IMPACT RESISTANT FOAM IS THE SECRET BEHIND FOURMULA®
Our chemists have developed a patented system that enables us to optimize the relationship between weight, durability & comfort. The patent protected process allows us to tailor the perfect ride that your feet will thank you for at the end of the day.
COMFORT WITHOUT COMPROMISE
The highly advanced FOURMULA® is a tri-blend of materials bonded together forming a highly wear-resistant compound. EVA alone has excellent shock absorbing benefits but poor wear-resistance. Rubber, although more wear-resistant, still has the tendency to wear or chip in large chunks, drastically decreasing the lifespan of the outsole. The FOURMULA® compound provides a flexible barrier against abrasion, scuffs, and scrapes; while also acting as a tough, protective layer against harsh elements. Depending on what your specific application is, the FOURMULA® blend can be configured for maximized flexibility, resistance and versatility. Regardless if you’re using it for the outsole or insole, it will offer you reliable durability, added strength and a product that will last 3 times longer than traditional rubber or EVA.
FOURMULA® doesn’t just grip, it latches to angled, wet, uneven surfaces for a strong stable ride. EVA is notoriously known for its lack of grip on wet or slippery surfaces, while rubber on the other hand is undoubtedly ideal in these same conditions. The extra weight of rubber comes with a price that your feet will ultimately be paying for. FOURMULA® blends together the perfect amount of rubber and EVA, maintaining the same gripping properties of a solid rubber sole, while maintaining the lightweight properties of the EVA.
Scientifically speaking, resiliency is the ability of a material to absorb energy when it is deformed elastically, and release that energy upon unloading. With standard EVA, repeated impact or deformation causes the resiliency to drastically decline over the lifespan of the shoe. Once this point is reached, your feet are left with no shock protection. You are essentially running on a flat. FOURMULA® resiliency has proven to outlast standard EVA foam by 3 times in our independent wear testing studies. The average lifespan of standard EVA foam is about 100 miles. FOURMULA® averages 300 miles before any noticeable flattening.
