good support but comes with its flaws
i love ON shoes, this is my 4th pair. support, fit and comfort are excellent. grip is ok BUT i find the grip very disappointing with wet surfaces. in particular on wet rocks the grip is way poorer than other shoes and sole technologies. given trail running is the primary purpose of this shoe, this is a significant flaw.
a minor gripe is that the laces are to long and you risk tripping easily unless you use the extra hole which i dont like.
