From featherweight REVlite cushioning to a no-sew welded upper, the 1770 is packed with cutting-edge technologies. N-ergy shock absorption extends beyond the crash pad into the midfoot to accomodate not only traditional heel strike runners, but also those who land on the midfoot. The performance-fit upper hugs the foot but is forgiving enough for most foot shapes, and modified Stabilicore medial support mildly stabilizes the gait so even light overpronators can sport this neutral-cushioning shoe.

	N-ERGY® in the midsole provides NB's most advanced shock absorption and cushioning
	Stabilicore® medial support system provides an extremely smooth transition from heel strike to toe-off
