Performance
The On Cloud X4 excels in multi-disciplinary workouts. The CloudTec® sole provides a springy response on the road, making it feel like you’re getting a little extra push with each step. They’re also stable during lateral movements, which is crucial for gym workouts. I’ve noticed that while sprinting, the transition from heel to toe is smooth, although for long-distance runs over 10k, you might find them a little lacking in cushioning.
Design & Build
The engineered mesh upper is both lightweight and breathable, keeping your feet cool during intense sessions. The shoe’s sleek design isn’t just for show; it’s genuinely comfortable, with a snug fit that isn’t too tight. Over several months of use, the material has shown excellent durability, maintaining its shape and support despite daily wear. The design is versatile enough to wear casually, adding to its value.
Value for Money
At $139.99, the On Cloud X4 is priced in the mid-range for performance shoes. Given its versatility, it’s a solid investment if you frequently switch between running and gym activities. While not the cheapest option on the market, the blend of performance, comfort, and style justifies the price. However, if you’re looking for a specialized shoe for marathon running or weightlifting, you might want to consider alternatives.
Durability
Having put these through the paces for several months, the durability is impressive. The outsole shows minimal wear, and the engineered mesh hasn’t lost its form or support. They’re easy to clean, which is a plus if you’re using them in dusty gym environments. The 12-month warranty gives an extra layer of confidence in their longevity.
✅ What We Like

One thing often overlooked is how well they perform on wet surfaces. The grip isn’t the best in rainy conditions, so be cautious if you’re planning to use them outside in unpredictable weather.
