These were my first On purchase having tried the shoe at the recent Running Show. I have a 56 mile Ultra event coming up so tested them with a 24mile Mendip run straight out of the box. The shoes were very comfy and I felt very confident in them from the start. The trail took in all types of terrain you could encounter - rocks, shale, grass, tarmac, gravel and mud. The shoes dealt with most of the terrains amazingly and I was confident to put my feet where I needed and not worry. However, muddy hills where there is no gravel or small rocks to grip to these shoes couldn't cope. Technical down hills were the worst slipping and sliding where other trail shoes I have had bite in and hold you. That said I completed the run and was very happy with the shoes. I will just need to check conditions before races to determine if the shoes are suitable for the conditions.
