Others, like Mark Thatcher's college summer job of guiding rafting trips in the Grand Canyon's Colorado River, have more widespread reverberations.
Thatcher is the founder of Teva (Hebrew for "nature"), the Velcro-strapped sport sandal that changed the way outdoor enthusiasts traversed rivers and mountains and has become a beloved icon in the outdoor community.
There are plenty more designs to choose from, including platform sandals, special pattern collections (like the commemorative Grand Canyon one), and hiking sneakers.
Whether you're hiking in a national park or walking around the city, it's almost impossible not to run into someone wearing a pair of Teva sandals (like the three Insider Picks members below, for example).
I tried my first pair a couple weeks ago, while Sally and Breton grew up running around in Tevas, and I can only envy them for being introduced to these sport sandals so early on.
