Smart comfort starts from the inside.

At CHK, comfort is more than a design detail—it’s the foundation of every sneaker we build. That’s why we’ve developed premium PU moulded insoles that deliver targeted cushioning, long-term support, and an adaptive fit that moves with you.

Whether you're on your feet for hours or simply seeking all-day ease, these insoles are designed to elevate the way you move.

What is PU Moulded Insoles?

PU (polyurethane) moulded insoles are crafted using advanced foam technology that offers high resilience, cushioning, and durability. This material compresses under pressure and springs back instantly—creating a soft, responsive feel underfoot. Unlike standard insoles, PU insoles retain their shape and structure over time, delivering consistent comfort wear after wear.

How Do They Work?

The science behind PU lies in its ability to balance softness and support. Our insoles are designed to absorb shock, reduce pressure on the feet, and minimize fatigue—especially in high-impact zones like the heel and forefoot. The foam moulds gently to your foot’s shape, offering a personalized fit that improves with each use. It’s also breathable and moisture-wicking, helping to reduce odour and keep feet dry throughout the day.

To ensure the best fit for every wearer, we offer PU moulded insoles in two distinct thickness levels. Thicker insoles deliver deep cushioning and added shock absorption—ideal for extended wear or physically demanding routines. Thinner insoles provide subtle, discreet support while preserving a closer fit—perfect for minimal or snug sneaker designs. Each option supports the natural movement of the foot without sacrificing performance or style.

Why Does It Matter?

The right insole doesn’t just add comfort—it improves posture, reduces foot strain, and enhances overall sneaker longevity. Research shows that insole thickness and material can significantly influence pressure distribution and walking efficiency. With our PU moulded insoles, wearers can choose the comfort level that best suits their lifestyle—without compromising on form or functionality.

More importantly, these insoles are built to last. Unlike traditional cushioning that wears out with time, our PU base resists flattening, ensuring a longer product life and a more sustainable wear cycle. That means less need for replacements and more value from every pair.
