By far the best grip in mud of any shoe I've ever run in. The almost complete lack of cushioning isn't an issue when it's muddy but as soon as the fields dry out they become far too hard to run in.

I've got narrow feet and find the fit great - not sure how wide footed people would cope though.

One of the other reviewers has mentioned quality problems and I've seen reviews on fell running sites that have raised the same issue. However, I've worn my pair for two winters now and have probably done 400+ miles in them and they are in remarkably good shape - apart from the laces snapping.

The same awesome grip as the other Mudclaw but a more padded and supposedly robust upper. I've done about the same amount of mileage in these as in my Mudclaw 270s (around 400 miles) but whilst the uppers on the minimalist 270s are fine the uppers on these are torn, cracked and on the verge of dropping to bits.

I did the 26 mile Belvoir challenge in them in Feb 2007 and wore a hole in the heel padding - and my heel was rather a mess at the end of the run. I've run similar distances in the 270's without having the same problem.

Also, because of the more padded upper they take almost three days to dry out when they get soaked - which frankly means every run in the Dec - March months.

I think the Mudclaw 270's are fantastic but that the 330 just isn't as fit for purpose.

This is rather a niche shoe. It is (sort of) a fell shoe with cushioning. The grip on mud is OK but not as good as an Inov Mudclaw. However, it's a lot more cushioned than the Mudclaw and on mixed terrain that includes harder ground it's a much more comfortable shoe to run in. I did a 26 mile trail / XC / Road race in them in Feb 2008 and they were ideal for the mixed terrain. The upper is very comfortable as well, and despite the padding dries out fairly quickly (although they smell revolting when they are wet). I was initially sceptical about the lacing system but I now think it is better than "normal"laces.

They were an absolutely great shoe for the wet summer of 2007 - there was a mixture of mud from the heavy rain but still patches of pretty hard ground and the Speed Cross was absolutely ideal.

I'm not a fell runner but I suspect that they might not work as a fell shoe - I ran up Jacob's Ladder in a pair and despite the cushioning there was little real under-foot protection and I ended up bruising the balls of my feet.

The other problem I had with them was that I wore them day in, day out last summer and after about 300 miles had destroyed the heel cusioning. However, I was so impressed that I immediately bought another pair.
