Say it...the shoes look shit. I love my trailfly 300 (despite nearly falling off the top of Tryfan) but they do look like i bought them from the Early Learning Centre. It's like the actively try to pick awful colours, but struggle to do that. There are smaller brands making half decent looking shoes (Norda, Mount to Coast).

Inov8 Trailfly 300G max, fell in love with this shoe. Currently on my second pair, and got a spare in the closet when these wear out

Just for statistics: I still really like them. After the updates to all the product lines they fit my feet even better. Luck of the draw I guess. First used the Trailtalon 235 in 2019 followed by two pairs of the Trailfly G270 V1 and a Trailfly G300Max. So I never wore the fell running models of the glory days everyone seems to miss so much. Now using Mudtalon Speed, Trailfly Speed and Max Models. They fit loose in the heel which you can counter with adjusted lacing. All of them are extremely durable with good grip. I also like the wider toe box. The look is quite dated and uninspiring though.

Can confirm the upper on Trailfly Max was the first and only point of failure.

To me they are still making solid shoes if you like a wider toebox. I get why fell runners who look for a very precise fit are upset about this, but I like to run long distances on a variety of trails without getting my toes crammed in a baguette shaped shoe.

I ran a lot in the G300 Max. Then I used different brands but have recently gotten TrailTalon both the regular and the Max due to the 6mm lugs. Especially the Max is quite enjoyable to run in.

The new shoes from Inov8 have quite good room in the toe box.

I really like the shape of their shoes. They also makes shoes that are great for muddy terrain. But the midsoles are dull and therefore I rather run in something like Prodigio Pro though they don’t have the same traction.

If the terrain is dry I would go with the Prodigio Pro any day in the week. But in mud the TrailTalon will have much better grip. I like the shape of the new Inov8 shoes but find them lacking a bit of rebound. The Prodigio Pro is fun to run and it feels fast.

I wear the Inov8 G300 Max for longer races and like them better than my Altra Lone Peaks..

The old Inov8 Trailfly G300 were perfect for this. They’ve been replaced with the new Trailfly but they have nowhere near as much cushion now and the max version with extra cushioning is a huge stack height so makes me prone to a rolled ankle. GYX shoes in my opinion aren’t great in the UK, bogs go in the top and you end up with your feet swimming because the water can’t get out. I much prefer a well draining shoe and a good pair of merino socks so you don’t get blisters My first trail she were the brooks cascadia which I’d I would recommend as a first trail shoe tbh. But for once you start doing more bogs/ deep mud/ grass etc they’re not great so are definitely a beginner trail shoe/ dry trail shoe (dry trail is hard to come by in winter though!)
