After a season off, the S-Lab Sense is back with the Salomon S-Lab Sense 2, a sub-7 ounce (6.7 oz/190 g), 4 mm heel-to-toe drop piece of trail running nirvana for your feet. Sliding on the Sense, it feels like the most comfortable of slippers, while providing a whole lot more protection. Salomon designed the Sense to meet Kilian Jornet's needs for the 2011 Western States 100... which he won.
While ultralight, quite flexible, low to the ground, and with a modest heel-toe drop, these are NOT "barefoot" shoes. They do provide a moderate amount of push-through protection and a decent amount of stability.
The second version of Kilian Jornet's race proven trail runner has gotten lower [9mm/13mm midsole heights], even lighter, and now gives an improved level of debris protection in an updated sockless fit package.
