For runners, spring and summer training is often a battle against temperature and humidity. On's "One System for Training" concept, launched this season, transforms the new generation Cloudmonster 3 with professional sportswear into a complete training system.
Like being pushed along in the clouds
The most significant upgrade is the three-layer CloudTec cushioning system. Previously, the biggest fear with thick-soled shoes was their "soft and weak" feel, but this shoe offers a distinct, layered cushioning experience: upon landing, the Helion super foam absorbs the harsh impact of asphalt. Then, the optimized Speedboard, combined with the pronounced arched sole, acts like an invisible seesaw, naturally shifting your weight forward. This is especially helpful in the later stages of long slow distance (LSD) training; when stamina wane and pushing becomes difficult, the forward rolling inertia saves considerable effort. Moreover, despite its bulky appearance, the shoe weighs only 240 grams, maintaining excellent cushioning without any heavy, cumbersome feel. Addressing the sweltering heat of spring and summer, the engineered knit upper features precisely designed ventilation holes, ensuring that even after running 15 kilometers in near-25-degree Celsius temperatures, your feet remain dry, without that burning sensation.
Say goodbye to friction and stuffiness
In summer training, a good sports bra is just as important as running shoes, because the friction after it gets soaked is a runner's nightmare. My first impression of this Performance Bra is its "smoothness." It uses On DryTec… 
The material has a very delicate feel, and the elasticity of the four-way stretch fabric makes the seams almost imperceptible when worn. It provides medium support, which is a good choice for most running training sessions because it allows for stable movement without being too tight to cause breathing difficulties at high heart rates. The I-beam mesh design on the back enhances heat dissipation in the back area, where sweat tends to accumulate, allowing you to feel the heat flowing quickly during running. Even more practical are its adjustable shoulder straps and fixed lightweight chest pads, solving two major pain points: firstly, you can fine-tune the tightness according to the day's training intensity; secondly, you don't have to struggle with shifted chest pads after showering. This thoughtful attention to detail, from wearing to washing, makes this gear not just a professional training tool, but also a considerate partner who understands your training struggles.

The core upgrade is the three-layer CloudTec cushioning system, making you feel like you're being pushed along on a cloud.

Then, the optimized Speedboard, combined with the pronounced arched sole, acts like an invisible seesaw, naturally shifting your center of gravity forward. This is especially helpful in the later stages of long-distance (LSD) training; when fatigue sets in and pushing becomes difficult, the forward rolling inertia saves you considerable energy. Moreover, although these shoes appear quite bulky, they weigh only 240 grams, maintaining excellent cushioning without any heavy or cumbersome feel.
