Inov-8 Mudtalon Speed V2 vs V1: Which Mud-Ready Trail Shoe Deserves Your Money?

Introduction

Winter trail running in the UK means one thing: mud, and lots of it. That makes this the perfect time to look at the Inov-8 Mudtalon Speed V2, the latest version of a trail shoe that leans hard into wet, sloppy, technical terrain. Inov-8 describes it as a mud tractor of a shoe, and the aggressive 8mm lugged outsole makes that clear the moment you flip it over.

To find out whether the new version is worth your money, we put the V2 head to head against the original Mudtalon Speed V1, running roughly four and a half miles in each shoe on the same rain-soaked route along the Cornish Coast Path. It is a route full of wet, slippery rock and deep muddy bogs, so it gave both shoes a genuine workout.

Test Setup: Two Pairs, One Route

The test was simple and fair. The outbound leg from Zennor toward St Ives was run in the V1 to refresh how the original performed, particularly its grip and traction. At the turnaround point, the V2 came out of a race vest along with a spare pair of socks, and the return leg covered exactly the same 4.5 miles on exactly the same route.

That setup allowed a direct back-to-back comparison of the new sticky grip rubber outsole against the old one, plus the feel of the updated upper. The weather cooperated too: heavy recent rain left the trail super wet and challenging, exactly the conditions these shoes are built for.

Mudtalon Speed V2: What Is New

The V2 is available from Inov-8 for £130 and comes in two fit options. The precision fit suits narrower feet, while a standard width fit is available for runners with wider forefeet or anyone who likes extra wiggle room up front. Thanks to Inov-8’s anatomical foot shape design, even the precision version has a decent level of toe box width.

The upper is built from a lightweight, highly breathable mesh that feels durable enough for harsh trail use, reinforced with overlays for structure and a substantial toe bumper for protection up front. The gusseted tongue is thin, but zonal padding down its center helps protect the top of the foot when laces are pulled tight, a small fix for comfort issues found in older Inov-8 shoes. New drainage holes either side of the toe box help water exit quickly, and the heel and ankle collar area now feels softer than before.

Underfoot, the midsole appears to be the same Powerflow Pro setup as the previous version, with an 11mm heel stack, 7mm forefoot, and a 4mm heel offset. Paired with Inov-8’s Boomerang footbeds, which add a thin layer of plushness and bounce close to the foot, it is a stripped-back shoe built for ground feel and connection rather than deep cushioning. The headline change is the outsole: a new and improved sticky grip rubber compound that Inov-8 claims delivers a 36% increase in wet slip resistance.

Mudtalon Speed V1: The Benchmark

The original Mudtalon Speed set a high bar. On the outbound run, it delivered loads of traction in the soft stuff, with the chunky 8mm lugs working brilliantly through deep mud. Grip on most types of rock felt pretty good too, and there was never a sense of the shoe letting go on technical sections.

There were only minor complaints. On one very greasy bridge, traction felt less certain and it was safer to stop and walk. Around the ankle and heel, the V1 felt noticeably stiffer, enough to cause a small amount of irritation on longer runs. As a benchmark for wet, muddy trails, though, the V1 remains a genuinely capable shoe.

On the Trail: How the V2 Performed

Straight out of the box, the V2 hugged the midfoot a bit tighter, likely just because it was new. The first real difference showed up at the ankle collar and heel cup, which felt softer and more comfortable than the V1. That extra forgiveness was welcome and appears to be a genuine upgrade for anyone who found the original a little stiff in that area.

On the muddy, rocky return leg, the shoe felt super connected, dialed in, and very stable. It is not deeply cushioned, but the Boomerang footbeds keep it comfortable, and only a few sharp rock edges pushed through the midsole over 4.5 miles. For distance, this kind of stripped-back shoe would suit efforts up to around half marathon, maybe 20 miles at a push depending on terrain.

Outsole and Grip: The Biggest Talking Point

Inov-8 claims the new sticky grip compound improves wet slip resistance by 36%, but honestly, the difference was hard to feel. The V1’s rubber was already grippy, and the V2 performed very similarly on the same terrain. If anything, it may be slightly stickier, but grip levels felt close to identical.

That is not a criticism of the shoe itself. The deep 8mm lugs delivered outstanding traction in mud and the new drainage grooves in the overlays visibly helped water escape up front on a route that was almost like a flowing river in places. The outsole does exactly what it is designed to do; it just may not represent a dramatic leap over the original.

Buying Advice: Upgrade or Stick With the V1?

If you already own the V1, the honest answer is that it is probably not worth upgrading. The performance difference is not massive, and the improvements are mostly comfort refinements: a softer heel cup and ankle collar, better drainage, and zonal tongue padding.

If you are new to this line and want maximum grip and traction for super technical, challenging, muddy winter trails, the V2 is an easy recommendation. It does that job extremely well, and after months in deeply cushioned shoes, the connected ground feel here is genuinely refreshing. At £130 it sits in a competitive price bracket, so it is worth comparing against other mud-focused trail shoes before you commit.

Conclusion

The Inov-8 Mudtalon Speed V2 is a confident update rather than a revolution. The softer heel and ankle collar, improved drainage, and zonal tongue padding make it more comfortable than the V1, while the aggressive 8mm outsole continues to excel in the wettest, muddiest conditions. The claimed grip improvement is difficult to notice in practice, so V1 owners can hold onto their shoes without regret. For everyone else hunting a mud-ready trail shoe this winter, the V2 is well worth a close look.
