loves me some smartwool
i now have 5 pairs of these guys. fit perfectly with both pair of my vibram 5fingers. keeps the stink factor at about a 3 rather than my normal 8. love them. they feel seemless on the toes. i will say that i got the large ones for a size 44 5fingers (10.5-11 US) and they come to mid-malleolus. tried on the mediums and they did not fit my toes as well. the micro is not exactly micro, not exactly a no-show sock, but i am still very satisfied with these and will buy more in the future. keep your eyes open too, you can find them for less than $15/pair.
