Hoka Cielo X1: Evaluating Speed Across Various Distances
The Hoka Cielo X1 is a lightweight, minimalist carbon racing shoe recognized for its exceptional speed and responsiveness. This model features an aggressive rocker design, a breathable knit upper, and a gusseted tongue, which collectively provide an enhanced racing experience. Our testing covered a range of courses from one mile to marathon distance, assessing the shoe’s capability to perform over varying lengths.
James’ Review of the Hoka Cielo X1
The Hoka Cielo X1 combines a winged carbon fiber plate with two layers of resilient PEBA foam, yielding a stack height of 39mm in the heel and 32mm in the forefoot, resulting in a 7mm drop. During initial testing in wet conditions on the track, the shoes felt comfortable and responsive, surprising James, who was new to carbon-plated footwear. The dynamic design encourages an accelerated pace but did present a minor issue with the laces coming undone during a training session.
In a follow-up one-mile time trial, the responsive nature of the Cielo X1 contributed to James finishing first with a time of 5:07.
Performance Evaluation of the Hoka Cielo X1
James aimed to break his club’s V40 record during a 5km Parkrun. With the shoelaces securely tied, he set out on a cold, dry morning. Although the shoes felt atypical at a slower jog pace, they excelled at speed. Over the course, he experienced no discomfort, leading to a record-setting finish time of 17:06—an accomplishment he attributes partially to the shoe’s performance.
5km and 10km Performance Potential of the Hoka Cielo X1
Following his record at the 5km distance, James, now eager to test his speed again, returned to the Bromley Parkrun with the aim of achieving a sub-17-minute time. With a strong field motivating him, he impressed himself with a finish time of 16:57, breaking another record in the V45 category and achieving his best 5km Parkrun time since 2012.

Darren’s Review of the Hoka Cielo X1
Darren is a long-time user of Hoka shoes, typically logging extensive mileage in models like the Clifton and Challenger. Excited to try the new Cielo X1, he noted its striking design upon unpacking. Initially accustomed to a size 10.5 in other Hoka models, he found the Cielo X1 to fit more true to size, opting for a standard size 10.
One of Darren’s reservations was regarding the rigidity of the shoe’s laces, which he felt could be problematic if not secured tightly. Despite this, he appreciated the comfort offered by the fixed mesh tongue design.

Pursuing Personal Bests with the Hoka Cielo X1
Darren aimed for a sub-20-minute time at his local Parkrun in order to push his limits. With the course’s favorable tarmac surface, he experienced excellent cushioning and a rolling feel due to the rocker design. He finished with a time of 19:10, showcasing the shoe’s effectiveness compared to other carbon racing shoes he has used, all while maintaining the comfort he values.
Testing the Hoka Cielo X1 in a Marathon
Darren took the Hoka Cielo X1 to the Rome Marathon, where he served as a pacer for a sub-4 hour group. Despite limited prior mileage in the shoes, he was impressed with their performance throughout the race. The lightweight design and carbon plate enhanced his pace at around nine minutes per mile. Darren finished strong with a time of 3:59:33, and notable was the lack of post-race fatigue, reinforcing his positive experience with the Cielo X1.
Final Verdict on the Hoka Cielo X1
For runners in search of a competitive racing shoe, the Hoka Cielo X1 presents itself as a comfortable option compared to many carbon-plated shoes available today. With its responsive PEBA foam and innovative rocker geometry, it caters well to both short and long-distance events.
