Sizing would be important. Would have to wear the Injinji socks with them and that adds thickness, but really helps with sweating. The last models with laces were Europe only, so I have to wonder if these will be the first US release? I am still not sure about the boot style. Not a big boot guy, but depends on the application. Maybe hiking. Maybe a year ago I would have jumped on this, but I just hate spending big bucks on a shoe these days; especially since there is so much choice... inexpensive... with Vibram soling material even!
