Waterproof
Waterproof: Waterproof clothes have the ability to keep rain out completely with a water column height from 10,000mm onwards. Mostly, these clothes are windproof, too.
Water repellent: Water repellent running clothes have a minimal protection against rain. The rain rolls off the jacket, but during heavy rain, the moisture may penetrate inside due to higher pressure. Mostly, these clothes are windproof. Active walking shoes may also be water resistant, and thus protect your feet against light rain.
Not waterproof: this clothes don't hold back rain and water. Most of our running shoes are non-waterproof. That's because they offer breathability, so your feet stay comfortable and fresh during running.
