APL Athletic Propulsion Labs' 'Ascend' sneakers are designed to suit all your training needs - the laces can be looped through in different ways to adapt the fit and support, depending on what exercise you're doing. This midnight-blue and black mesh pair has a signature feather-shaped Propelium® sole, which provides superb cushioning underfoot and has an 8mm drop from the heel to the forefoot to keep your feet in a natural position.
