All of you joggers out there probably know that Brooks makes some of the best running shoes around. What you may not know is that the company now makes enviro-friendly sneakers, too. The new Brooks Cascadia 2 running shoe is made from so-called "green rubber," which uses silicon rather than petroleum for a more environmentally friendly product. Petroleum-based rubbers not only use up fossil fuels but are also rumored to release carcinogenic dioxins during production.

Designed in part by vegan marathoner Scott Jurek, the Cascadia 2 shoe lets you go trail running guilt-free. And though running shoes aren't typically valued for their style, I think these are kind of cool looking—you know, for a running shoe. You can buy the Cascadia for $95 here.
