Has anyone tried them? I'm looking for a lightweight preferably low heel drop trail shoe that can accommodate orthotics and is suitable for marathon/ ultra distances! Off road shoes I have tried so far are: saucony xodus - not bad but too heavy and clumpy and I keep getting a hotspot/ blister on arch with long distances! Adidas kanadia: too stiff Ran in them once and didn't like them Asics trail attack: blisters on toes and arch! Inov8 mudclaws: great for mud but most of my running is mixed terrain NB 110s : these would be brilliant if I could fit my right orthotic in it!!!
