I know, I know, this has all been done before and there are many threads that sort of answer the question but hopefully someone can offer specific advice and also, others on the subject seem to be out of date.
I am doing an off road ultra (55 miles) in December even though I did an 86 miler last year and am only just getting over 30 miles per week after a knee injury sustained in that (my fault, should have listened to my body and stopped). The terrain is quoted to be 95% off road and according to last year's participants it was pretty boggy.
I am a big lad (6ft 14St) but have done ultras and quite a few marathons so I am not concerned about completion but I want to go in as well prepared as possible. I currently do anything muddy in Adidas Kanadias (?) but I am not sure I would like to do 55 miles in them, most I have ever done in them is 24 miles and it hurt (although half was on the road so I only have myself to blame).
I want some decent off road shoes, at the moment I have adidas supernovas, Asics Nimbus, Sketchers something and some Decathlon shoes for on the roads. I did a parkrun the other day in some Nike Pegasus as well. These are the sort of shoes I normally wear, neutral, cushioned.
I have looked at what is out there and originally I was thinking about Innov8 X-Talon 212, but have since found out they are very low drop and not great for long distances. Maybe the X-Claw?
