It's going to be sunny on 8.31.2008, so don't forget to wear your shades. Gear up for the Nike+ Human Race with Impel. These performance sunglasses give runners a hyper-light, secure-fit. The tint makes everything crisp and sharp, but is also relaxing and soothing on your eyes. And the lenses won't fog or bead sweat. A few additional specs:

-Adjustable ventilated nose bridge for improved airflow, reduced slippage and fogging
-Cam-action spring hinges lock into place
-Nike Flying Lens Technology for reduced fogging and consistent visuals
-Magnesium, secure-wrap temples and waffle pattern grips to enhance stability and comfort
