Inov-8 Terra Ultra G270 shoe review


Last updated: 09-Mar-21

By Alice Morrison

The great thing about lockdown in winter in Scotland is that there is no excuse not to get out on the Pentland hills. I am stranded with my parents temporarily in Edinburgh and for the sake of all our mental health, I am out on the trails daily. Where I am, after 20 minutes or so on the tarmac, I am actually on miles of hard-packed paths with a great variety of rocks, grass, mud and rabbit holes, with bonus extras at the moment of ice and snow. Ideal conditions for testing out these inov-8 Terra Ultra G270s.  The ideal use for them is hard and rocky paths and trails.

Pros: What’s good about the inov-8 Terra Ultra G270

The shoes look good coming out the box and initially I am worried that they will be too narrow as they are very streamlined, but in fact I have plenty of room in the toe box. They are super light and when standing my toes are right off the ground with my mid-foot well supported and my heel cupped in firmly.

They are light and bouncy. The manufacturer claims good statistics on energy return and I could actually feel that in my feet, which was fantastic. This is a comfortable shoe. I am testing them in winter so breathability was a moot point, but I liked the moulding at the siders which gave me protection higher up on my foot.


inov-8 is clear that these shoes are more for trails and hard rocky surfaces than mud but I think they are actually underselling their grippability. I really liked them on the rocks and the stony trails both up and down, but they were also great on wet grass and – surprisingly – the slushy snow with hidden patches of ice that just love to take your feet from under you. That graphene works.

Everyone has a different preference for cushioning versus feeling the ground under them. On trails and hard pack over long distances I think a middle path is a good one and this shoe gives you that. There is enough cushioning to keep that energy coming and ward off some of the pain that is inevitable over longer distances but you can still feel the ground underneath. The mud cleared well from the lugs.


Cons: What’s not so good about the inov-8 Terra Ultra G270

I’m going to start with the minor quibbles. There was no heel loop so I had to wiggle them a bit to get them on and I found the laces loosened and had to be retied, also the tongue was a bit skimpy.

After a long day with added walking spells, I had some heel pain on the left hand side, so for me could have had a bit more support on the heel. That is a trade off though with drop and touch to ground.

They are not a cheap shoe but are comparable with similar in their class. I agree with inov-8 that this is not a shoe for hard core mud.



A great shoe for the trail. I liked the balance between support and ground feel and I loved the grip. This shoe helps your feet and I did feel that energy bouncing back through my legs. Use it for what it is designed for – hard trails, packed earth and rock and I think you will really enjoy it and feel the benefit.

Design 9/10

Overall 9/10

I enjoyed the review and it helped me decide to but these shoes. They are AMAZING and tick the boxes in almost all that I would want in a running shoe. Comfortable, allow the toes to spread out when travelling fast downhill so that there is less chance of going over the edge of the foot; cushioned enough so that I can run 5km on tarmac with no problems but able to feel the texture of the trails so that you can enjoy them; grippy -perfect on the trails it is designed for and I only slipped on some thin mud over wet grass on a slope where I always seem to slip regardless of the shoe. The only criticism I can think of is the tongue is a bit short so the knot laces sometimes sit at the very edge and top of the foot. They also dry out well and clean easily. very comfortable as slippers around the house- if I could get away with it!
