To answer the original question, Xero have a new minimalist shoe with enough tread for some off-trail and mud. Looks like a decent all-rounder, and is a candidate as a thru-hike shoe.

Lot’s of very positive reviews and a fairly decent price. The sole has a 5000 mile guarantee! Which I presume really means that it is guaranteed for the life of the upper. For those of us in Europe, there’s a UK website too. Not the best looking shoe, but function trumps fashion and I’m going to give them a shot.
I’ve tried the NB Minimus but found the tread was lacking – for groomed trails only, I think.
The other main option is the Vivo Primus Trail. Reviews are saying that they have finally overcome the problems with durability. I’ve been badly bitten in the past, though in their defense they did give me a couple of complementary pairs to compensate.The Vivos work out more expensive than the Xero, but to my eye are a much better looking shoe.
As for pounding on rocks, I think that most of us will need to be pragmatic. My longest trip so far in minimal shoes was 30 days on tough high-alpine trails – often very stony or rocky. I did this hard-core in Vivos. By the end my feet were a bit tender – not enough to spoil the trip, but I was hobbling a bit after stops till my feet warmed up.
So since then I’ve been experimenting with inserts for differing conditions. For road walking I use a 1mm insert of an impact absorbing foam, just to take the edge off the hardness. I don’t think we evolved to walk barefoot on asphalt… If I’m facing a long passage of rock, I also add my home-made rock plates. Currently I’m using plastic from thin kitchen chopping mats I bought at a pound shop. Cost next to nothing and seem to work pretty well.
For me, minimal shoes add a lot to the hiking experience – I feel more connected with the country I’m moving through. I also have a much-injured ankle, and find that the low stack-height is safer and more stable. I’ve worn nothing else for years so should be fully transitioned, and am hoping to refine my system to the level that I can complete major thru-hikes without any undue discomfort.
If I find I need more protection on multi-month trips I’d try the Atra Lone Peak. Much more stack height that I’d like, but at least it’s a zero drop shoe. Very popular with US thru-hikers.
Have any of you done big miles in minimal shoes? I’d be interested in your experiences.
