Yep, hadn't looked at that thread since...
Well, it's a 100-mile race - so my feet were pretty battered after nearly 24 hours, but I was relatively comfortable. The furthest I'd run in them before the NDW100 was 11 miles so it was a massive gamble to use them in a 100... I remember my achillies got a bit sore at around 30 miles but I got through that OK.
Having used the MT110's a lot since then on long runs from road, mountain, fell and trail I find that after 4-5 hours my achillies gets tight, but it always seems to go away after a while and I don't feel any after effects...
My "road shoes" are Brooks Green Silence, and I actually prefer less cushioning and heel drop these days to be honest, I guess it's just something you get used to after a while.
