Inov-8 Terraclaw 220 - comfortable racing flat for light trails

80 / 100 by Lars Wichmann • Level 3 expert

Starting off with the design, the Inov-8 Terraclaw 220 comes in blue/light blue with orange contrast, and a black with dark red contrast. The black model, in particular, is very stylish and has won several design awards.

The tongue is special; it is asymmetrical turning inwards instead of straight down to your toes.

At first, it looks weird - but after a while, you learn to appreciate it. When it comes to looks, the Terraclaw 220 is without a doubt the favorite in my current arsenal.

 

 

Comfort

I'll categorize Terraclaw 220 as a semi-all-round trail shoe, with one leg in the racing flat end of the spectrum. They are light, low stack, small drop (4 mm) and true to size with plenty of room to wiggle your toes.

The asymmetrical tongue adds to the comfort because it works well at redistributing the tightness across the instep (at least for me).

They are a bit cumbersome to put on as they require more-than-normal untying before you are able to slide your foot in. Once on your feet and tightened, the shoes will stay exactly where they are  - more so than normal.

 

 

With usage, your shoes will start to widen in the toe-box area.

You'll probably find yourself unable to tighten the laces properly over the metatarsals. This will be annoying to some people. I don't mind too much as I prefer an open toe box and thick socks (e.g. Thorlo Experia).

 

Outsole

If you read the official description, there are all sorts of weird inventions and various compounds going into the sole. In my experience, its all a bit theoretical, and I put it down mostly as marketing gimmicks.

There are some decently sized and spaced lugs, which will give you some traction on soft and reasonably flat tracks, as well as on rocks where they work well. On sandy and muddy sections, you'll survive, but it's not recommended either on roads.

 

 

The 220 got no rock-plate so to some extent "you feel the track", which I find nice.

What is annoying is variations in the rigidity of the two compounds that make up the sole. If you hit a hard object along the edges or on the heel (red sections) you'll just notice it.

If you hit it with the center of the forefoot (black sections), it will push straight through to the soft tissue between the first and second metatarsals. Man, that hurts! I have more than once hurt my feet on pebbles while running on gravel roads. Once I even had to walk home and take a few days off running.

 

Upper

The spacious upper is made of a nice, soft open weave fabric, which keeps your feet well ventilated. They are excellent for dry summertime runs on tracks and road-to-track type stuff.

The open weave, however, lets in fine-grained sand/grit and water easily. The water leaves quickly too, but the sand stays behind. Most of my runs are in coastal areas with plenty of sand (dunes) around, and even with gaiters on I am able to restock the kid's sandbox with about half a cup of sand after each run.

There is a wee bit of toe bumper to shield your feet - but nothing that will give any real protection should you venture up/down mountains or riverbeds.

 

 

Performance

The Terraclaw 220 is categorized by many reviewers as the racing flat version of the Inov-8 Terraclaw 250. They are right; its a lightweight and fast shoe.

On average my runs in Terraclaw 220 has been 5-10 seconds faster than my general average. However, that may well be because I only use the Terraclaws on lighter trails, thus penalize (speed-comparison-wise) my more rugged trail shoes who take the brunt of the muddy mountainous slow runs.

I have used my Terraclaw 220 for road-to-trail type runs up to 20+ km, and I wouldn't mind going further than that. It is quite comfortable - also in the long run.

 

Durability

My first pair is right now at 760 km and about to retire - mind you I have also used them a bit for normal wear (walking and at work). There is a fair amount of wear on the outsoles, not so much the upper.

The main reason for retiring my 220s is the inconsistent sole rigidity, which has increased with milage. I simply don't dare run in them anymore for fear of injuring my feet. I got a second pair very cheap on sale a few months back - otherwise, I'd probably not buy another pair of Terraclaws.

 

Conclusion

The Inov-8 Terraclaw 220 is a very nice looking and comfortable shoe with a somewhat limited usage spectrum.

Fast and perfect for easy trail runs in dry conditions. Not my first choice for wet/muddy/sandy trails, nor rugged/technical and roads. They let sand, grit, and water in very easily, and the inconsistent sole rigidity is annoying bordering on "deal breaker".

I like the novel asymmetrical tongue both design and comfort wise, but it's not for everyone, and it certainly requires "getting used to".

Hi, I'm a recreational ultra trail runner doing some 2000+ km per year, almost exclusively on trails. I did my first marathon in 1995 and my first ultra in 2001. I run to exercise my body and relax my mind. I love to reach that blissful state when there is nothing but you and the trail, and once you get to your destination you can't recall how you got there and how much time has passed. I'm a gear-freak and running shoe aficionado and regularly browse the web for inspiration and good deals.
