hat shoes may have been used long before this, but because the materials used were highly perishable, it is difficult to find evidence of the earliest footwear.[9] By studying the bones of the smaller toes (as opposed to the big toe), it was observed that their thickness decreased approximately 40,000 to 26,000 years ago. This led archaeologists to deduce that wearing shoes resulted in less bone growth, resulting in shorter, thinner toes.[10] These earliest designs were very simple, often mere "foot bags" of leather to protect the feet from rocks, debris, and cold.

Many early natives in North America wore a similar type of footwear, known as the moccasin. These are tight-fitting, soft-soled shoes typically made out of leather or bison hides. Many moccasins were also decorated with vari
