Running shoe review: inov-8 Roclite 315 GTX trail shoe, £145

RRP. £145, Amazon (£115-135)

Waterproof shoes tend to be heavy, cumbersome and about as breathable as a plastic bag. So the inov-8 Roclite 315 GTX represents something of a step change. Based on the much-loved Roclite platform, it offers 100 per cent waterproofing in a lightweight, low-profile package.

If you’re running a 5K, or think that wet feet is all part of the off-road running experience, you’ll want to look elsewhere. However, for those who like the really long stuff, or for the growing number of people embracing ‘fastpacking’, the prospect of a waterproof shoe is a highly appealing one.

As with all inov-8 models, the grip on the Roclite GTX is exemplary. Designed for multi-terrain running, its lugs aren’t quite as pronounced as those on the Mudclaw or X-Talon, but there’ll still keep you upright when the going gets muddy.

The waterproofing is similarly impressive. While the Mudclaw is water-resistant, the Roclite GTX is 100 per cent waterproof. You could walk around in a (very shallow) bath in these things and come out with dry feet.

At 315g, they’re a tad heavy for quick running (by comparison, a lot inov-8s fell running shoes weigh in at less than 250g), but compared to most hiking boots, they’re impressively lightweight. The 8mm drop also makes them feel more like a running shoe than a walking one, while the red and black styling gives them a racing edge.

The problem your tester had was with the sizing, which led to the blackening of a toenail. I experienced something similar with the highly regard inov-8 Terraclaw 220 – a shoe loved by many others – so it could be that my feet are just unsuited to certain types of inov-8 models. That, or I was wearing a size too small or too big. Either way, it’s worth making really sure of this before making a purchase – because, at £130, these things are a big investment.

Still, if you’re looking for a waterproof shoe in which you can walk as well as race – and you can get the sizing just right – the Roclite 315 GTX ticks many of the right boxes.

Personally, I ended up going for a different solution for my recent  fastpacking adventure along the South Downs Way: the inov-8 Mudclaw – a trusty favourite – paired with some waterproof Sealskinz socks.
