I want to start trail running as I generally run on roads etc I am six 3 height and weigh 17 stone. I am a neutral shoe and wear asics nimbus for road running. I like the look of asics trail elite and the adidas kandia elite. But then I was wondering do I need a pair that are goretex lined. Any advise on any good trainers would be welcome budget upto ??80 max would prefer around ??60 mark thanks Craig.
