Learn about the thinking at the core of every Chaco sandal.
Your Feet.
Chaco's trademarked BioCentric comfort starts with a biomechanically correct contour that distinguishes Chaco footwear from all the rest, creating a level of foot health that has been awarded the Seal of Acceptance by the American Podiatric Medical Association (APMA). More importantly, BioCentric comfort and support are qualities Chaco wearers experience with every stride. Understanding the elements of that stride, and addressing how best to support and optimize it continues to be at the core of everything Chaco designs. Chaco's BioCentric comfort ensures a supported, comfortable stride in any activity.

1. Heel Strike
The fatty pad under your heel bone is a very effective natural shock absorber. All Chaco footbeds are designed to concentrate this pad for optimal cushioning and comfort. Footbeds that are very soft or lack structure allow the pad to flatten and lose its resiliency.

2. Initial Pronation
Pronation is another way your foot absorbs shock. There is a ligament called the plantar fascia that connects your heel to your forefoot. The arch of your foot is like a bow that flexes. The plantar fascia is like a bowstring. As the foot is weighted, the plantar fascia tightens. The key is to prevent the foot from over pronating and stressing the plantar fascia.

3. Neutral
Neutral position occurs when your foot has pronated slightly and the bones are lined up to work efficiently to propel you forward. The aggressive footbed contours of Chaco footwear are designed to stabilize this position all the way through toe-off.

4. Mid-Stance
As weight moves through the arch, Chaco footbeds provide subtle support to the metatarsal bones, reducing fatigue. |

5. Toe Off
The breakpoint, flexpoint and toe spring must be correctly engineered for each type of footwear. All footwear needs substantial toe spring to facilitate a smooth, natural step. |
