My latest running shoes are Inov-8 Oroc 280s courtesy of Run4It.
I used these for both the Mugdock trail race and Pentland Skyline, and although marketed for orienteering, they are equally suitable for trail and hill running. At first glance they look a bit like the X-Talons, but on closer inspection they are a good bit more robust with more substantial midsole, and have an interesting widely spaced tread with tiny metal studs designed to grip on wet rock and in snow and ice conditions. So you get an interesting clattering sound when running on hard surfaces, making it tricky to creep up quietly behind someone on tarmac.
The Oroc 280s were instantly comfortable and gave no blisters or burning heels at the Pentland Skyline. I should be giving them another outing at the British Hill Relays in Fife on Sunday.
