On Cloud X 4
Are you looking for men's sports shoes that can handle circuit training in the gym as well as a quick run outdoors? The On Cloud X 4 in black is designed for such versatility. Its lightweight construction and stable fit keep your foot secure during lunges, jumps, and directional changes, while the cushioning absorbs impacts when running. Thanks to its understated design without unnecessary embellishments, you can easily wear it outside of training as well.
The midsole features CloudTec technology. This consists of the brand's signature hollow elements that compress upon landing to soften the impact, while they firm up during takeoff to support a dynamic stride. The upper combines synthetic materials with textiles, ensuring a secure fit while allowing for breathability. The rubber outsole grips both gym floors and asphalt. The black color can be effortlessly paired with training shorts, leggings, or a tracksuit. The Swiss brand On was founded in 2010 in Zurich by former triathlete Olivier Bernhard and two friends, and has always emphasized its unique approach to cushioning.
