My old driveway was sloped, but my new one is 30 to 35 degrees. Can be fun just wrestling a full trash bin down the driveway when it's dry out.
First shoveling couple of weeks ago I looked a bit like the video that @Kiss4aFrog posted, so I ordered some slip-on cleats. Wow! Game changer, and something I will own from now on. They're the HIGH-PRO model from Winter Walking, and I bought them from a small family-owned business in Pennsylvania. Super nice guy on the phone, and shipping was fast and free. https://www.slipresistant.net/products/high-pro.html
