Panther Teeth (pantherteeth.com) has developed and patented a “lace lock” device that can be used on all types of athletic footwear, boots and ice skates. The device enables the athlete to customize the fit of their footwear by creating separate zones of lace tension, while keeping their laces at their preferred tension level during their entire workout. Now a user can customize the fit and comfort of their footwear to create more power, balance and stability. The Panther Teeth system enables faster, more powerful directional changes through a seamless connection between an athlete and their footwear. We offer this product as a DTC (direct to consumer) product and we have another version for the OEM's. The OEM version can be permanently attached and moveable along the length of the tongue. Panther Teeth lock down on laces to: • Prevent laces from loosening to retain the same level of tightness from start to finish of your workout • Create a tighter hold where you need it without sacrificing comfort or performance • Adapt to the unique characteristics of your foot providing a more customized fit • Eliminate any side-to-side movement of your foot within your footwear
