Is the Saucony Xodus Ultra 4 good for ultrarunning?
Yes. The Saucony Xodus Ultra 4 is a comfortable, protective choice for long trail runs and ultras, with lively cushioning, a stable platform and grippy Vibram MegaGrip. At 309g, it is not especially light, and its tapered fit may not suit every runner. It is better for steady distance than racing fast.

What is the Xodus Ultra 4?
The Saucony Xodus Ultra 4 is a cushioned trail shoe designed for long training runs, ultras and demanding mountain days. It combines a PWRRUN PB foam core with a PWRRUN frame, giving it a lively ride with a broad, protective platform. Saucony lists a 36mm heel and 30mm forefoot stack, a 6mm drop and a weight of 309g for a men’s UK 9; RunRepeat measured 312g in the lab. Its reinforced mesh upper includes gaiter attachment points, while the Vibram MegaGrip outsole has 4mm chevron lugs.
How does it perform on long runs?
Reviewers found the cushioning comfortable and consistent over distance, with enough protection for rocky trails without completely losing trail feel. Live for the Outdoors and RunRepeat describe a stable, lively ride suited to steady efforts rather than fast racing. The Vibram MegaGrip outsole grips well on rock and easier terrain; RunRepeat’s lab review measured traction 12% above average. Thick mud is less suitable, as the lugs can clog. The shoe’s 309g listed weight is also a trade-off for its protection, and reviewers note that laces may loosen during use.
Who should buy the Xodus Ultra 4?
This shoe is a strong option for ultrarunners and trail runners prioritising comfort, protection and grip on long training runs or mountain days. The Saucony Xodus Ultra 4 should particularly appeal to runners who want a cushioned platform for rocky routes and easier terrain, rather than a lightweight shoe for racing at speed. Its tapered, relatively narrow fit may not suit wider feet, so fit is worth considering before buying. Reviewers also flag concerns about heel-padding durability. Listed UK prices vary from £140 to £150.

Frequently asked questions
How does the Saucony Xodus Ultra 4 fit?
Reviewers describe the fit as tapered and relatively narrow, so it may not suit runners who prefer a roomier toe area or have wider feet. The upper is reinforced mesh and provides a secure fit, but try the shoe on if possible before committing to long runs.

The reinforced mesh upper is intended for demanding trail use, but reviewers raise concerns about heel-padding durability. They also note that the laces may loosen or come undone. The available review data does not provide a specific lifespan or mileage estimate.
How does the Xodus Ultra 4 compare with its predecessor?
The available reviews do not establish a detailed predecessor comparison. They highlight the Xodus Ultra 4’s PWRRUN PB core, PWRRUN frame and Vibram MegaGrip outsole with 4mm lugs. For this model, reviewers’ main verdict is that it prioritises cushioning and protection over a light, fast ride.
