Our lightly-textured silicone earpieces use the all new Goodr Cat Tongue Technology to offer enhanced protection against slippage. Our frame is crafted to be feather-weight, yet snug, with a comfortable fit to prevent bouncing when running. Glare-reducing, polarized lenses and UV400 protection that blocks 100% of those harmful UVA and UVB rays. Look like a model while you run. Is that not why you take all those running selfies? We aspire to the day we can guarantee that you will not 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.
