Saucony Xodus Ultra Review & Sizing Guide

Published Updated

Buy Xodus Ultra 4 for a max-cushion Saucony trail trainer with strong wet-terrain grip and a forefoot bounce that supports half-marathon trail PRs; skip it if you have wide feet that loved the OG Xodus Ultra width, or if you cannot try them on first given the blister-and-numb-foot risk over long distances they gave me this huge blood-filled blister, which has never happened to me in any other shoes.

Full breakdown

Saucony Xodus Ultra is Saucony's max-cushion trail shoe, sitting one tier above the Peregrine and aimed at ultra distances and road-to-trail mileage. The current Xodus Ultra 4 brought back fan-favorite ride and grip after the Xodus Ultra 3 was widely panned as too narrow I know that Xodus ultra 3 was a flop; maybe the Xodus ultra 4 is worthy?. Buy it as a cushioned ultra trainer with PWRRUN PB-style bounce and aggressive grip; do not buy the Ultra 3 generation, and do not expect OG Xodus Ultra width.

FAQ

Is the Xodus Ultra 4 a good road-to-trail shoe?

Yes, owners specifically buy the Xodus Ultra 4 for the road-to-trail use case, and the question shows up clean in r/trailrunning. A Tucson buyer with a sidewalk-to-dirt-trail commute pattern asks the community directly and gets affirmative answers live in Tucson AZ and go from sidewalk/pavement to dirt trails. Would you recommend this for what I'm looking for?. The aggressive lugs are still soft enough to handle pavement transitions, and the cushioned stack absorbs hardpack better than a Peregrine. If most of your weekly miles are split city sidewalk and singletrack, Xodus Ultra 4 is a stronger pick than Peregrine 15.

How is the Xodus Ultra 4 different from the Xodus Ultra 3?

Owners are explicit that the Ultra 3 was a step backward, and Ultra 4 corrected the fit issues. The OG Xodus Ultra wide-foot fan thread calls the Ultra 3 too narrow overall Saucony Xodus Ultra 3 - Unfortunately too narrow overall for me, and the Xodus Ultra 2 replacement thread frames Ultra 3 as a flop with cautious optimism for Ultra 4 I know that Xodus ultra 3 was a flop; maybe the Xodus ultra 4 is worthy?. If you tried Ultra 3 and gave up, the Ultra 4 deserves another in-store fitting. If you are buying blind, do not assume the Ultra 3 fits like the OG.

How does the Xodus Ultra 4 compare to the Asics Trabuco Max?

The Xodus Ultra 4 wins on grip and forefoot bounce; the Trabuco Max wins on rear cushion. A direct half-marathon trail PR review compares them in detail and gives the Xodus the advantage for cornering and confidence in wet terrain, while admitting the Trabuco Max has more heel cushion bounce under forefoot is perfect, so is the cushioning. Bounce under heel is fine, cushioning is not so good as the Asics Trabuco Max3 but the shoe is way way grippier en faster. In wet terrain you can cut corners way faster and with more convidence. Choose Xodus Ultra 4 if your routes have technical sections; choose Trabuco Max if you mostly run flatter cushion-priority trails.

Are there fit or comfort issues to know about for ultra distances?

Yes, and you should demo or short-run before committing to a race. One owner reports horrible foot pain, numbness, and a huge blood-filled blister after just one training run and an easy-paced marathon, ending in DNF at 75K both feet went completely numb — I could barely feel them and it honestly felt like they were about to fall off. On top of that, they gave me this huge huge blood-filled blister. That is one owner, not a brand-wide pattern, but it is a real risk signal that the fit can fail in unpredictable ways at long distances. Build up gradually before any 50K-plus race day.

Should I buy Xodus Ultra 4 if I loved the original Xodus Ultra?

Probably not without trying them on first. The OG Xodus Ultra was a wide-foot fan favorite with a roomy toe box, and the post-Ultra-2 generations have all been narrower. A heavier 200lb wide-foot owner who burned through their OG Xodus Ultra stockpile is now in Altra Experience Wild and Topo Ultraventure 4 rather than newer Xodus Ultras I absolutely loved the original Saucony Xodus Ultras, but I've finally run through my stockpile and need to find a new go-to trail shoe. If wide fit is your hard requirement, look at Topo Ultraventure 4, Altra Olympus, or Hoka Speedgoat 6 wide instead.
