Full review
Max-stack cushioning performance
The midsole configuration features a unique RelieveSPHERE geometry that creates a wave-like curve across the sole, designed to diffuse impact forces from uneven terrain. However, the Energy Foam midsole compound shows signs of being outdated, with energy return figures of only 47.6% in the heel and 51.6% in the forefoot, significantly below industry averages. This low energy return creates a more compliant but less responsive ride that may disappoint runners seeking a dynamic, springy feel for faster-paced activities.
The plush cushioning is particularly effective for long-distance trail running and hiking, where comfort over extended periods becomes paramount. During testing, the shoe demonstrated superior shock absorption in rocky and uneven terrain, with testers noting that the wavy sole design effectively rolls over sharp objects without causing discomfort. This design proves especially beneficial for runners who experience heel bruising or foot fatigue on technical trails, as the cushioning system appears to effectively distribute impact forces across the entire footbed.
Despite the impressive cushioning, the shoe's performance in energy return reveals a significant compromise. The low rebound characteristics of the Energy Foam compound mean that the shoe does not efficiently convert kinetic energy back into forward motion. This results in a ride that feels more like floating over terrain rather than propelling forward with momentum. Testers noted that while the plushness is appreciated for comfort, it creates a sensation that is more suitable for recovery runs or slow-paced hiking rather than competitive trail running or fast-paced training sessions.
Fit and upper construction
The Ultra Glide 4 features a premium upper construction that balances comfort with security, though it does present some challenges for certain foot types. The shoe runs true to size with a notably roomy forefoot and toe box, which provides comfort for runners with wider feet. However, the midfoot area maintains a snug fit that may feel restrictive for those with narrower feet or those who prefer a more flexible upper. The plush upper material is surprisingly breathable, even during extended trail sessions, with testers noting minimal overheating issues during hot weather runs. The Quicklace system functions reliably without requiring frequent adjustments during runs, though some users reported initial tightness that resolved after a few wears.
The upper construction includes a well-padded tongue that provides additional comfort around the midfoot area, helping to prevent pressure points during long runs. The material shows good durability in trail conditions, maintaining its integrity even when subjected to abrasive terrain. Testers noted that the upper material held up well against hard impacts and did not show signs of premature wear during typical trail use. The volume in the forefoot area allows for natural toe splay, which is beneficial for runners who prefer more toe room. However, the snug midfoot fit may cause issues for runners who require more flexibility in that region.
Fit characteristics vary significantly based on foot width and running style. The shoe's design favors runners with regular to wide feet, as the forefoot and toe box provide ample room for comfort. Testers with narrow feet found the midfoot constriction to be limiting, particularly during high-intensity runs. The heel counter provides solid support and stability, though the overall upper construction does not offer the same level of lateral support as more traditional hiking shoes. The plush upper material creates a cradling effect that many runners found comforting, but the snug midfoot section may cause discomfort for those who prefer a looser fit throughout the entire foot.
Traction and outsole performance
The outsole design represents a significant evolution from previous Ultra Glide models, featuring a modified lug pattern that balances grip with durability. The Contagrip compound delivers solid traction on moderate inclines and well-maintained trails, with testers noting good grip on loose gravel and rocky surfaces. However, performance on extremely slippery or muddy conditions shows limitations, with some testers experiencing minor slippage on wet rocks or loose scree.
The outsole's performance varies across different surface types, with the most notable improvements coming in technical trail sections where the deeper lugs provide better bite. Testers found the shoe performed exceptionally well on smooth, well-groomed trails where the rockered design allowed for smooth transitions. The tread pattern also provides adequate grip for downhill running, though the shoe's plush cushioning can make it feel less stable on very technical or steep sections. The full contact outsole design contributes to consistent traction, but the relatively shallow lug depth limits performance in extreme conditions where aggressive tread patterns would be more beneficial.
During extended testing, the outsole maintained its grip characteristics well over time, with minimal wear observed even after numerous trail runs. The lug configuration effectively channels water away from the contact points, improving performance in wet conditions. However, the shoe's traction performance does not match that of more aggressive trail runners or technical hiking shoes, particularly in scenarios involving loose rock or muddy surfaces. The modified tread pattern does provide a good balance between versatility and specialized grip, making it suitable for most recreational trail activities but less ideal for competitive or technical mountain running.
Weight and overall performance
This weight-to-cushioning ratio makes it one of the lighter max-cushioned trail shoes available, with testers noting that the shoe feels surprisingly light despite its 41mm stack height. The weight distribution is well-balanced, with the plush forefoot cushioning not adding excessive bulk to the overall footprint. This makes the shoe particularly appealing for runners who value lightweight options without sacrificing comfort.
Performance across different terrain types demonstrates the shoe's versatility, particularly in long-distance applications. Testers found that the shoe excels in smooth trail running and hiking scenarios, where the rockered design and cushioning system work together to provide a comfortable ride.
