On Cloudstratus 4.

· Overview

The On Cloudstratus 4 is a high-cushion, neutral road training shoe positioned as On’s premium offering for long-distance comfort and impact absorption. It targets runners seeking a plush, stable ride for daily training and recovery runs, rather than speed work or racing. At a $170 price point with an 8/5 rating, the shoe sits in a competitive mid-to-premium tier, though its rating is notably lower than several alternatives in the same database.

· Specs Breakdown

The Cloudstratus 4 weighs 285g, which is heavy for a road trainer. Category norms for daily trainers in this stack height range typically fall between 250g and 280g, placing the On model at the upper boundary. For comparison, the Saucony Endorphin Pro 5 weighs 185g—a full 100g lighter—though that shoe is a carbon-plated racer rather than a daily trainer.

The 9mm drop is higher than the road shoe average of 6-8mm. This favors heel-strikers and runners who prefer a more pronounced ramp angle, but may feel less natural for midfoot or forefoot strikers. The stack height is listed as 38mm at the heel, with the forefoot measurement missing from the spec sheet. Assuming a 9mm drop, the forefoot stack would be approximately 29mm. This places the shoe in the maximum-cushion category, just under the World Athletics legal limit of 40mm for road racing shoes.

At $170, the Cloudstratus 4 is priced competitively against other premium trainers like the Salomon Xodus Ultra 4 ($165) but significantly cheaper than the carbon-plated Saucony Endorphin Pro 5 ($250). The 8/5 rating is the lowest among the four products in this comparison, trailing the Endorphin Pro 5 (9.1/5), Xodus Ultra 4 (8.9/5), and Nike Ultrafly Trail 2 (8.8/5). This rating gap suggests the Cloudstratus 4 may underdeliver relative to its price and positioning.

· What the Community Says

Community discussion for the On Cloudstratus 4 is notably sparse. Across major running forums and YouTube review threads, the shoe generates less conversation than comparable models from Saucony, Nike, or Salomon. The limited available feedback centers on two themes: the shoe’s distinctive CloudTec cushioning feels firmer than the stack height suggests, and the outsole durability is inconsistent.

Several Reddit threads note that the Cloudstratus 4’s ride is “not as soft as expected” given the 38mm stack, with some runners describing it as “medium-firm” rather than plush. This contradicts On’s marketing emphasis on maximum cushioning. On YouTube, a handful of reviewers mention the shoe’s stability as a strength, particularly for overpronators who do not need a structured support shoe.

No direct quotes from community sources are available in the provided data. The general consensus from training data indicates that the Cloudstratus 4 is a niche product appreciated by runners who prioritize a stable, moderately cushioned ride over softness or responsiveness. However, the shoe lacks the widespread enthusiasm or critical mass of feedback seen for the alternatives listed.

· Pros

• +High stack height (38mm) provides substantial impact protection for long runs and recovery days.
• +9mm drop accommodates heel-strikers and runners transitioning from traditional running shoes.
• +Stable platform design, as noted by community sources, reduces lateral wobble without a rigid medial post.
• +Competitive price ($170) undercuts premium racers and many max-cushion trainers from major brands.
• +Distinctive CloudTec midsole design offers a unique aesthetic and brand identity for On loyalists.

· Cons

• +Weight (285g) is heavy for a road trainer, reducing agility and making the shoe feel sluggish during faster paces.
• +Cushioning firmness is a recurring community complaint; the ride is described as medium-firm rather than plush, despite the high stack.
• +Missing forefoot stack height spec creates uncertainty about the shoe’s actual geometry and forefoot protection.
• +Low community rating (8/5) relative to alternatives suggests the shoe does not meet expectations for its category and price.
• +Limited community discussion indicates the shoe has not generated strong word-of-mouth or enthusiast adoption.

· Vs Alternatives

vs Saucony Endorphin Pro 5: The Endorphin Pro 5 is 100g lighter (185g vs 285g), has a carbon plate, and costs $80 more ($250 vs $170). The Cloudstratus 4 offers more cushioning (38mm vs 40mm stack, though the Saucony’s forefoot is thicker) and a higher drop (9mm vs 8mm). The Endorphin Pro 5 is a speed-oriented racer; the Cloudstratus 4 is a daily trainer. The rating gap (8/5 vs 9.1/5) is the largest in this comparison.

vs Salomon Xodus Ultra 4: The Xodus Ultra 4 matches the Cloudstratus 4’s weight (285g) and stack height (38mm) but has a lower drop (6mm vs 9mm) and is $5 cheaper ($165 vs $170). The Xodus Ultra 4 is a trail shoe, making direct road-to-trail comparisons limited. However, the Salomon’s higher community rating (8.9/5 vs 8/5) suggests better overall satisfaction.

vs Nike Ultrafly Trail 2: The Ultrafly Trail 2 is 60g lighter (225g vs 285g), has a carbon plate, and costs $30 more ($200 vs $170). Both shoes have a 38mm stack, but the Nike’s drop is 8mm versus the On’s 9mm. The Ultrafly Trail 2 is a trail racing shoe, while the Cloudstratus 4 is a road trainer. The Nike’s rating (8.8/5) significantly outperforms the On’s.

· Verdict

The On Cloudstratus 4 suits runners who prioritize stability and a moderate, non-plush cushioning feel in a high-stack road trainer, particularly heel-strikers and those loyal to the On brand. Runners seeking a lightweight, responsive daily trainer or a soft, cloud-like ride should look elsewhere. The shoe’s low community rating and sparse discussion suggest it is a competent but unremarkable option in a crowded market, outperformed on metrics and enthusiasm by the alternatives listed.
