Classic shape with new levels of style and performance. We designed these shades to look good and fit comfortably on your face whether you’re haulin’ tail down a mountain trail or drinking scotch in Loch Ness.
Developed to be lightweight and comfortable, the OG Running Glasses are the perfect partner for any run. Ideal for both trail and road running, the sunglasses feature a no bounce frame which ensures a comfortable and secure fit. The frame is snug and lightweight and offers a perfect fit to prevent bounce when running so you’ll always remain comfortable and distraction-free. The frame has also been constructed using a special grip coating which helps to eliminate slippage when sweating so the glasses will always stay put on hot and humid days. As well as this, the Goodr OG’s feature polarized lenses which are glare-reducing and provide UV400 protection that blocks 100% of those harmful UVA and UVB rays. Completing the sunglasses are a scratch-resistant layer which protects the glasses from harm.
FITTING AND ADJUSTING TIPS
How to measure your foot length
- Stand with the heel to a wall and put a measuring tape under your feet
- Read off the measured foot length in millimeters before your longest toe
- If you are between two sizes, choose the next higher, because feet are minimally greater under load

Your feet should be able to move freely without your toes hitting the edge of the footbed.
Before trying them on, put one hand under the toe and one under the heel, then flex the footbed a few times. This will initiate the break in period and will your help your new sandals feel comfy sooner.
Open all straps and step into the footbed. Close the straps comfortably, leaving enough space to allow your feet the freedom of movement. Exhale and enjoy.
For the first five or six times you wear your new footwear, limit the time to just a few hours. This allows your feet and body to gradually get used to the contoured arch support as well as the straps and buckles.
