Born in Zurich, Switzerland in 2010, the footwear brand "On".
Developed by a former triathlete and an engineer, its proprietary "CloudTec" cushioning system has garnered widespread attention from athletes to the fashion industry.

In this article, we focus on the "On Cloudsoma," a trail running shoe designed to pursue a sense of unity with nature among the brand's extensive lineup.
We will delve into its unique materials and construction (its appeal as a product) and thoroughly explain the sizing, which is often a concern when purchasing.

1. The Concept and Proprietary Technology of On Cloudsoma

The On Cloudsoma is a model developed for light off-road running and shorter, authentic trail running.
It was created for runners who want to seamlessly blend into nature and run with a clear mind, unbound by pace or distance.

The greatest appeal of this shoe lies in the following innovative technologies.

• CloudTec Connect™ Cushioning System: It flexes in tandem with the natural movement of the foot, providing real-time sensory feedback from the ground.
• Helion™ HF Hyperfoam: Optimized to make it easier to grip the ground, it delivers a comfortable and stable running experience.

2. Materials and Structure from a Craftsmanship Perspective

The On Cloudsoma features a precise structure that combines functional beauty with practicality.
The upper utilizes a sock-like construction, providing a firm hold on the entire foot.

The outsole is equipped with "Missiongrip™", a reliable feature even in harsh environments.
This delivers exceptional traction and grip on uneven terrains such as wet ground, mud, and gravel paths, supporting a stable toe-off.

3. Sizing Guide for On Cloudsoma

We will explain the "On Cloudsoma sizing," which is the most crucial factor when choosing shoes, based on a review from actual wear.

• Overall Fit: If you choose your usual size, the toes will fit perfectly, but the design feels slightly snug around the width and instep height.
• How to Choose by Use: For serious sports applications, we recommend your usual size for a secure fit. On the other hand, if you prefer a relaxed fit for daily wear or town use, we recommend going half a size up.
• Excellent Hold: The collar is designed to be narrow, securely holding the heel in place. Therefore, even if you size up by half for a looser fit, the heel is unlikely to slip, maintaining a comfortable wearing experience.
