Runner's World Best BuySpring Shoe Guide 2017" The Ravenna has long been a moderately supportive and cushioned shoe, capable of handling both long runs and tempo runs with ease. This year, Brooks is labeling it as one of its Energize" shoes, recommending it as the stability sister shoe to the Launch. The shoes now feature a number of similarities, such as 5.5 mm of blown rubber in the forefoot for a softer ride and springier toe-off, and an X-shaped patch of rubber in the midfoot that smooths the gap between the heel and forefoot. A new air mesh is more breathable than previous versions, but the upper still has plenty of structure to hold the foot steady, thanks to an adjustable strap that locks into the laces.
