This is the 3rd Vibram I bought in a year, i thought i'd better go with a model with thicker soles this time so I bought the Treksport. ( I have been distance running for years and once I went Vibram I didn't wanna go back to conventional running shoes ever again.)
It is as comfortable as the Komodosport and Bikila's I bought, and as other reviewers pointed out, more protective when you step on small stones etc. on the trail, just the right amount thicker on the outer sole so I am expecting these ones to last more than the 4-5 months which is the duration after which the other 2 models got holes on the soles and had to retire.
The seller is trustable, this is without a doubt original and in original packaging and shipped an hour after I ordered.
