Just a few words on these. I like minimal shoes. My favourites were Vivobarefoot Neo Trails ... but they aren't so easy to get now. The only problem with them is that on stony tracks, they offer little protection from painful bruising if you happen to land hard on a sharp stone.
I recently bought a pair of Merrell Bare Access GTX shoes (about 63 quid from Amazon). They are stiffer than Vivobarefoot and have a layer of impact protection. They are also waterproof. There is, I think, zero drop from heel to toe.
So far they have been excellent. There isn't quite the same feedback as a barefoot shoe...but that's not such a bad thing when the feedback is painful. There is still decent ground feel. Lugs are 4mm and give good grip on everything but the slickest mud. The are very comfortable, with a wide toe box. Sizing is on the small side...go up a half or full size.
They feel really well built and durable. I would say a great everyday shoe...especially in wet weather. I'm not sure whether Merrell are persevering with their trail shoes. I hope so.
