A footware company in the Czech Republic is getting ready to produce and sell its own re-creation of mountain boots found on Ötzi the Iceman, whose 5,300-year-old well-preserved body was discovered in the Italian Alps in 1991. (Hey, I finally figured out how to type German umlauts!)
(You can find more information on Ötzi—also spelled "Oetzi"— here. On that page, do a find for a "" to find a link to another article about the Czech footware company's plans to manufacture the Oetzi shoes. For some reason, I wasn't able to link to it from this blog.)
Apparently, the shoes got "rave reviews from mountain climbers and backpackers" as being comfortable and shock-absorbing. Then again, when I was a young thing, I could wear flip-flops or kung fu slippers all day without getting sore feet. Not anymore!
