I've just ordered a pair of Neo Trails. I've lived in my brown Aquas for the past 18 mnthos and find it hard to wear much else, other than a 2 year old pair of Vibram FF classics which are falling apart now. I also recently had to ditch a pair of old merrell mountain boots wearing them for a day was really uncomfortable and stressed my knees and ankles. I'm hoping the Neo Trails can replace mountain boots as they look the sturdiest of all the barefoot gear out there. As a pretty minimal person, I'm hoping I can get by on a pair of Achilles, a pair of Ras (eventually, to replace the Aquas) and a pair of Neo Trails for all my footwear needs.
