inov-8 MUDCLAW 300 Shoe Review

C’mon, get a grip! If you run in mud, you will no doubt be familiar with inov-8. For years, inov-8 has provided the ‘go-to’ shoes for running when the ground gets wet, slippery, muddy, gnarly and so on!

The Mudclaw 300 is not a new shoe in the massive inov-8 line up. The 2015 incarnation though does have a wicked and eye grabbing colour way and having used many versions on inov-8 (fave the 212 here) I was keen to put the Mudclaw 300 through its paces. Believe it or not, I am (was) a 300 virgin!

Red, blue and a white logo. Have to say, inov-8 does a great job of getting shoes to jump off the shelf. I love this colour way and yes, it makes me want to wear the shoe. If you have the previous version of the ‘300’ in yellow and black, don’t be fooled into thinking this is the same shoe. It’s not.

The sole and heel have had a revamp. The previous model really flared up at the rear, the new incarnation (red and blue) sits much closer to the ground, does not flare up and the heel box sits lower so as to cause no problems with the Achilles.

It’s still a 2-arrow shoe, so, 6mm drop.

Drop is a personal thing but I am a firm believer that 6mm/ 8mm drop shoes provide a great middle ground and if you are running longer, a slightly higher drop is kinder on the calf and legs. Of course, this is all down to personal preference. If you don’t know what the drop of the shoes you run in is, it’s worth finding out. Going too low too soon could cause injury.

The sole has 8mm lugs. If Wolverine™ wore run shoes he would most likely go for the Mudclaw. Yes, they are grippy buggers. The rubber compound is soft and grippy but be warned, the shoe is called Mudclaw for a reason, you want to keep hard ground and abrasive surfaces to a minimum in these shoes as the sole WILL wear down. My test run includes 1-mile of road before and after the trails and I have to say, this shoe feels wonderfully comfortable on the hard stuff despite its ‘off-road’ pedigree. You can actually hear the sole grip. Sounds weird I know, but it’s very clear and you can feel it. At the front of the shoe, just behind where the toes would sit is a clearing in the sole with a META-FLEX™ this allows the shoe to bend without restriction when running. Works great when climbing!

As the name suggests, the weight of the shoe is 300g. inov-8 always name the shoes based on the weight of a UK8.5 in case you didn’t know. It’s a pretty cool system actually as you can see at a glance, based on weight, if a shoe may or may not be suitable for you.

The upper is treated with DWR coating and has a ‘Precision’ fit. Let’s be clear here, inov-8 now makes many shoes in a ‘standard’ and ‘precision’ fit. If you have a wide foot, this is good news because you may now well be able to wear a shoe that you were not able to wear in the past. But for me, the Mudclaw and shoes like it are all about control and precision. A shoe for really muddy and technical conditions should hold your foot and allow no movement. You need that controlled feel. Control gives precision and precision means faster running and less mistakes. Of course I am giving a very personal opinion here but I hope you see the logic? What I am saying is, be careful when choosing a shoe. Precision for my relatively wide foot is great when I need it but I wouldn’t want to be running all day with my toes cramped into a shoe. For me, the Mudclaw although precision in fit still had a relatively roomy toe box and this was great on the technical muddy stuff.

The tongue is held in place by elastic to stop it slipping. It’s a great move. However, the Mudclaw  doesn’t fit as tightly or as snug as say the Salomon S-Lab Sense SG (the perfect fitting shoe for me!) but if laced correctly (try this), pulled tight and double knotted your foot should feel super secure; my feet were!

Getting lacing right is particularly important as the heel box has been tweaked so that it sits lower on the Achilles Tendon to avoid tension and potential injury problems. On my first run I felt as though my heel was slipping and I was unsure if this was a good move. Once re-laced, tightened appropriately, I can confirm that the lower heel is a good idea.

The rand around the lower part of the upper is now stitched and should in principal last longer and be more durable. Toe protection is relatively minimal.

The sides of the shoe are reinforced with a series of zig-zag support (webbing upper support) to hold the foot in place and these extend to the back of the shoe. They do the job, I had no issues with feeling that I had any lack of support.

Cushioning for me is one of the key factors of this shoe. I have long been a fan of the 212 (here) but when running longer I found it just a little too minimal. Not so with the 300. The EVA foam, 6mm drop and Meta-Shank all work together to make this a great shoe for longer days out. The stack height is 28mm and therefore considered low but obviously not as low as some. It has average stiffness that works exceptionally well on varied terrain. It has no rock plate but does have a performance last and Met-Cradle.

The shoe is as you would expect in an out-and-out off road/ mud shoe fits NEUTRAL.

In Use

My first run in the shoe was mixed. I found my foot moved around a little and I felt insecure with the lower heel. When I got home I looked at the shoe, re-laced it and then the following day went out and ran the same 8-mile loop. It was a completely different experience.

First and foremost, these shoes grip and really grip. If it’s wet and muddy these are now my go to shoe. I recently ran an uphill and downhill trail in Ireland that was on the Mourne Skyline MTR race route and the trail incorporates many elements – forest path, tree routes, gravel, stone steps, mud, road and it had rained heavily before the run and drizzled whilst running. At no point did I have any question on grip! For a shoe that is designed to keep you secure on muddy trail, I was amazed at the security on wet and slick rock. I can’t emphasize enough how important this is. You need that 100% reassurance so that you can relax, the the Mudclaw 300 gave me this.

Although a precision fit shoe, I found the toe box roomier than my inov-8 212. No bad thing and it certainly caused me no issues. The added cushioning was superb when running longer or when getting off soft ground and on to harder trails. Certainly a shoe I would choose when training or racing longer.

6mm drop for me is perfect and the stack height of the shoe made me feel 100% confident; no rolling! Depending on your experience, preferred distance and ability, the Mudclaw 300 is a perfect training shoe that will keep you happy for many a run. I personally would be more than happy racing in it over any distance. For the more experienced, they may well prefer a slightly lighter shoe? The Mudcaw 265 for example is 35g lighter, has the same outsole and 3mm drop.

Summary

The Mudclaw 300 is a shoe for when you need grip. It’s comfortable, secure, provides excellent traction and if laced correctly will hold your foot firm. It’s not a shoe for running on the road even though it’s remarkably comfortable. Just keep in mind, the more you run on the hard stuff, the quicker the sole will wear out. My daily training run has 1-mile of road out and back and I have been using the Mudclaw 300 on a regular basis. I currently can see minimal wear after 80-miles. The shoe is true to size. I wear a UK9.5 and the inov-8 fit perfectly in the same size.

What inov-8 say:

The legendary all-terrain animal has undergone a makeover for SS15. Now boasting the same flatter heel unit as the mudclaw™ 265, but still maintaining its 6mm drop, the mudclaw™ 300 also has an improved, more flexible upper. A fully gusseted tongue helps keep any debris out. Its hero-status outsole remains as aggressive as ever, guaranteeing the ultimate grip for mountain, obstacle and adventure racers on the muddiest, steepest terrains. Website HERE

  1. Did the Ice Trail Tarentaise last year in these ones. The yak trax obligatory anti slip device is completely useless comparing the grip we get from the Mudclaw 300 . I never put on the crampons and was hammering down on the Grande Motte Glacier (3600m altitude) all out with not one slip.
    Honestly the shoe is very durable, well cushioned and the grip just had to be mentioned in every single sentence I write 😀 Actually I did the Templiers Endurance Trail 2013 (until 95th km) in these as well. Performed perfectly on hard packed surface too !
    Enjoy your Mudclaw Ian ! https://www.youtube.com/watch?v=Sh-KAzRxQc4

  2. If you put mudclaw 300 on a scale and compare it with mudclaw 265 you will notice no difference in weith. Both are about 265g in size UK 8. Good old days when number in a shoe name meant something are over…

  3. Wow, I didn’t find them true to size at all, quite the reverse.

    I have large feel, though not particularly wide. I found that the 12 (my normal size) were cripplingly small, my toes horribly crunched up in front, as well as the midfoot a little pinched. To say that they came up short is an understatement- they were worse than Adidas short. I could barely hobble in them- let alone run!

    Since they don’t seem to sell a 12.5, I had to get a 13 in the end. It needs some faffing with the laces, to lash them down to a secure fit in this size, but at least it doesn’t feel like I will break my toes as soon as there’s any ground impact.

    Now I have a pair that I can get on, they are formidable. They’re a one trick pony for the nastiest type of British weather- but they do what they do wonderfully. The grip on muddy hills inspires a lot of confidence, in a situation where my Salomon trail shoes would start suffering a lot of wheelspin.

    The only real downside is that I find that I prefer to carry them and change, rather than wear them down on pavements and roads, which is a logistical faff. However, they do exactly what you’d expect, once you get a pair that fits.

  11. hi ian–terrific review! i’ve been thinking about these shoes. do you think they would work well doing double duty for hiking (not especially technical)? or would the larger, spread-out lugs not be so great for that? if so, any suggestions for a really good trail running/hiking shoe?

    thanks,
    bruce
