NO SLIP - Our lightly-textured silicone earpieces use the all-new goodr Cat Tongue Technology to offer enhanced protection against slippage. NO BOUNCE - Our frame is crafted to be feather-weight, yet snug, with a comfortable fit to prevent bouncing when running. ALL POLARIZED - Glare-reducing, polarized lenses and UV400 protection that blocks 100% of those harmful UVA and UVB rays. ALL FASHION - Look like a model while you're running. Isn't that why you're taking all those running selfies? NO CATCALLS - We aspire to the day we can guarantee that you won't be whistled at on the street; sadly, we cannot make that guarantee. We CAN, however, guarantee that no person wearing Runway goodrs has ever been telephoned by a cat.
