Topo Athletic Ultraventure 4: First Run Review of the Updated Trail Shoe

Introduction

Topo Athletic has been on a strong run lately. After a road shoe from the brand left a genuinely good impression earlier in the year, plenty of runners asked for a look at the latest trail offering, and that brings us to the Ultraventure 4.

The shoe was still close to its UK launch at the time of testing, with a retail price of around £150. The test pair, a UK 9.5, weighed 310g and arrived in a bright Miami blue, navy and orange colorway. Plenty of runners love bold colors, though more understated options are typically available once a shoe launches.

Spec Overview

The Ultraventure 4 carries over a lot from the well-liked Ultraventure 3. The midsole uses the same ZIP foam construction with a 35mm heel stack and 30mm under the forefoot, giving a 5mm heel-to-toe offset. Underneath, the shoe gets a Vibram rubber outsole with the same 4mm lug pattern as before.

One thing worth flagging: this is not Vibram’s Megagrip rubber. Instead, it is the XS Trek compound, so grip was a genuine question mark going into the first run. On the evidence of this outing, the concern was mostly unfounded, but it is a detail worth knowing before buying.

Upper and Design Changes

The biggest changes arrive in the upper. It is still built from recycled engineered mesh, but now in a dual-layer setup: an internal layer with small perforations for airflow, plus a structural overlay wrapping around the ankle collar and a more substantial cradle down the sides. The goal is extra support and durability compared with the previous version.

Padding in the gusseted tongue, ankle collar and heel feels plush without being excessive. Two small loops at the top of the tongue help the laces create a secure midfoot lockdown, and there is a gaiter attachment system with two points on the heel cup and one at the bottom of the laces. A toe bumper adds protection up front for rocky trails.

First Run Impressions

The first outing covered just shy of eight miles, starting with a mile of tarmac before reaching the trails. The shoes felt good from the very first steps. True to size, the UK 9.5 was spot on for length, and the anatomical, foot-shaped design left plenty of wiggle room in the toe box while the midfoot and heel stayed locked down with no slippage.

Across the full run there was no irritation and no rubbing, and the padding felt just right: plush enough for comfort, but not so soft that lockdown suffered. The fit and comfort package earns a clear thumbs up.

Upper Fit and Comfort

Fit is where Topo consistently stands out, and the Ultraventure 4 is no exception. The wide, anatomical toe box lets toes splay naturally under impact, which matters more the longer you run. The secure midfoot lockdown held for the entire distance, which is exactly what you want from a shoe pitched at longer trail days.

The dual-layer upper also gives the shoe a more finished, durable feel than the outgoing version, and the added structure around the collar should pay off on descents where feet tend to shift inside the shoe.

How It Handled the Terrain

This run threw a real mix at the shoe: a couple of miles of road, soft sand, stony and rocky trails, a bit of mud and even wet, slippery grass. The ZIP foam midsole felt comfortable on compacted trails and road sections, and the deep stack delivered solid underfoot protection while still feeling connected to the ground.

The Vibram XS Trek outsole was the pleasant surprise. It gripped well on greasy tarmac and wet rocky sections, and the 4mm lugs gave good traction in soft sand and light mud. For truly boggy, deep-mud conditions, the shallower lug depth is not ideal, so this is not the shoe for extreme winter glop. But for nearly everything else, it performed well.

Verdict After the First Run

The Ultraventure 4 delivered a feel very similar to Topo’s well-received road shoe, just in trail form: a comfortable, great-fitting upper, roomy toe box, secure lockdown, and a midsole and outsole combination that handled varied terrain with ease.

These are early impressions from one run, but the profile points toward longer distances in drier spring, summer and autumn conditions. The wide anatomical fit and comfortable stack make it a credible candidate for trail days and even ultra-distance racing up to 100 miles, especially on routes mixing road and trail sections. A full in-depth review will follow once more miles are in the bank.

Conclusion

The Topo Athletic Ultraventure 4 is an encouraging update: familiar, proven underpinnings with a more supportive and durable upper, and an outsole that handled mixed terrain better than expected. If your trails lean toward dry, varied ground and you value a roomy, foot-shaped fit, this deserves a spot on your shortlist.
