- This invention relates to an innovative design of footwear, in particular a lightweight sandal for running.
- For thousands of years, man has built, various types of footwear to protect feet against stones, gravel, and other sharp objects that impact the foot. Early designs of sandals led to shoes and then to sneakers. But modern footwear can be confining and uncomfortable. Recently, a movement has started to return to minimalist footwear, leading to a resurgence in the use of sandals.
- Huarache Sandals, pre-Colombian in design and origin, were worn by indigenous Mexicans for centuries. Indigenous people built these sandals with leather soles and laces. Although many lacing styles existed there were several used by the Native Tarahumara Indians for running sandals. These thong, strap styled huarache sandals used ¼″ wide leather laces that weave underneath the leather sole, around the ankle., and ultimately are tied with slip knots back on themselves on top of the foot.
- Although this ancient lace tying method enables the wearer to completely customize the fit of their sandals, it is also difficult to master because of the intricate knots involved. This invention brought forth replaces the ancient system of knots with a singlet adjustment device (buckle). The singular adjustment device enables the huarache wearer to have their cake and eat it too by preserving the incredible adjustability of ancient huarache lacing but at the same time making the means of adjustment easier.
- However, sandals typically are not designed for rugged use as a running or a hiking shoe. The strapping is not rugged enough nor is it designed for the custom fit that is required for running and hiking. The present invention addresses this need for a. rugged, comfortable sandal.
