Altra's flagship all-mountain shoe is back for 2020! The Lone Peak 4.5 is the same bomber thru-hiking, trailing running, off-trail exploring monster as the popular 4.0 version, but with an updated upper that resolves durability weak points and simplifies the lacing for better adjustment. Like all Altras, the Lone Peak features the extra wide "Foot Shape" toe box and zero-drop geometry. The burly MaxTrac rubber outsole is back for the 4.5, and the high-traction lugs are unchanged. This is our first recommendation for anyone looking for thru-hiking or trail running footwear!
