Hi MM
I've been using these for almost a year now and they are absolutely fantastic IN THE RIGHT CONDITIONS. The trail surface is key though. If its soft underfoot, grassy, claggy, muddy, or on fells where comfort is second to grip these shoes are second to none. Don't expect to enjoy the road sections joking the trails though as you'll feel every lug of the very aggressive sole pressing through the sole.
I've actually found NB110's to be surprisingly good as an intermediate shoe, also better than expected in the clag.
I had to go a size up in the baregrips in comparison to my previous Inov8 shoes mind you so it may be worth popping to a shop.
