Of all the shoes in the inov-8 range, the MUDCLAW is one of the most iconic. 
An evolution of our very first shoe – the MUDROC launched in 2003 – the MUDCLAW performs exactly how the name suggests... it claws through mud.


Aggressive 8mm studs sink like teeth into all muddy ground, delivering unbeatable grip and stability when running over what is usually such a slippery type of terrain. Such is the strategic positioning of the multi-directional studs, the MUDCLAW then exits the mud having freed all dirt from its outsole. This means its fangs remain at their most fierce, ensuring consistent outstanding grip with every stride, no matter how deep or prolonged the mud may be. 

Given its proven ability to perform in mud and over all soft ground, it’s no surprise that the MUDCLAW is the shoe of choice amongst many trail, fell, mountain, cross-country and obstacle runners preparing to tackle the most testing of sloppy underfoot conditions, across all gradients of slope. Uphill, downhill, or on the flat, the MUDCLAW gives the runner the confidence necessary to attack whatever lays ahead, safe in the knowledge that they won’t end up slipping. 

Added to this – and significantly enhancing its versatility – the MUDCLAW also grips to rocks, including the dreaded wet rock often found on trails, fells and mountains. The DUAL-C compound used (a mix of medium and hard sticky rubbers) combined with the larger surface area on the tips of the studs, provides a stable, confidence-boosting hold when running over hard, wet ground.


A precision-fitting upper and MET-CRADLE system hug the foot and ensure minimal internal movement. This is a big advantage when running downhill or contouring, as it stops the toes and feet from being bashed about. This provides protection from the inside, while from the outside, a rand wraps all the way around the upper and toe bumper area, preventing loose stones and stray rocks from injuring the foot. 

The MUDCLAW in the current range is the MUDCLAW 300, which weighs 300g and features both a 6mm drop (heel to toe differential) and an injected EVA midsole. The outsole at the heel sits flat to the ground to increase stability. There is also a MUDCLAW 300 CLASSIC, featuring the original rounded bi-planar heel, which is available through selected retailers in the UK.


Rhys Findlay-Robinson wore the MUDCLAW 300 throughout his 2016 British Fell Running Championship series victory. 
He says: “For the high fells, where I love running, it’s perfect for my needs. It has an aggressive grip which is necessary to give me confidence on the roughest and steepest descents, and is a bit thicker than a lot of fell shoes, which adds extra protection from loose rocks and scree. Added to this, they are so durable you can get some really good mileage out of them.”

Ever since its introduction to the range, the MUDCLAW has won countless awards. The most recent came in December 2016 when Totally Active Magazine named the MUDCLAW 300 as its Editor’s Choice. The magazine says: “If you like to run on the wild side, you simply can’t find a better shoe than the inov-8 MUDCLAW 300. Their grip is truly staggering and I’m yet to find another shoe that comes close.” Read the full review here. Image shows the shoe in its previous colour (red and black). The new colour for Spring/Summer 2017 is yellow and black.


The most aggressive outsole in the inov-8 range boasts 8mm studs that deliver the best grip possible over muddy terrain.

Nothing grips better in mud. Aggressive 8mm studs claw through all mud-sodden terrain and come back up begging for more.


The multidirectional stud pattern ensures mud is released quickly from the outsole, so the studs are always able to deliver maximum grip with every step.


A Dual-C combination of medium sticky and hard sticky rubbers ensure the studs stay strong over time and continue to deliver.


The rand that wraps around the shoe's upper and toe bumper ensure outstanding protection against stones and other debris.
