Good to know
- The lightest fully-waterproof trail running shoes on the market, Topo Athletic Hydroventure shoes offer robust performance and breathable comfort for off-pavement workouts.
- With an outsole that offers multi-directional lugs, forefoot flex grooves, and a mud-release technology, there is optimized traction for durability and maximum grip.
- Featuring an EVA midsole with a flexible thermoplastic urethane plastic for protection against sharp rocks and roots while delivering a smooth and responsive ride.
- The upper presents an original eVent technology, which is a waterproof and breathable membrane that consists of nylon mesh and printed polyurethane.
As the design of the Hydroventure includes a stack height that runs high around the midfoot and lowers down around the forefoot, the shoe runs small and it is recommended that runners getting half a size up their usual shoe size. The structure of the shoe is geared towards neutral pronators, but with its wide toe box, the Hydroventure can accommodate up to a high-volume foot. Width profiles available are D – Medium for men and B – Medium for women.
The Hydroventure’s outsole is made of sticky rubber and features aggressive, wide-breaking lugs for tricky downhill traversals. This sticky rubber compound is also used in the Hydroventure 2 running shoe.
Coming in a size of 4.5 mm, these multidirectional lugs allow for natural foot function all throughout while providing an optimized and aggressive traction. It is designed to be flexible and to work efficiently for all types of terrain.
Flex grooves are added to the forefoot section. These indentations accommodate the natural bending of the foot as it gears toward the toe-off phase of the gait cycle.
With a 5-mm heel-to-toe drop, the midsole of the Hydroventure is designed to encourage natural loading and foot motion during the gait cycle. The cushioning leans on the firm side, but it still aims to offer a comfortable ride.
There is also a TPU add-on called the ESS rock plate and it’s embedded in the midsole foam. It is made to protect the foot against jagged rocks and other trail hazards that can potentially injure the foot while delivering a smooth and responsive ride. It also has a segmented design to allow for flexibility.
The upper of the Hydroventure employs an exterior mesh that is durable and tightly woven. It utilizes a welding technology that eliminates overlaps, as well as the need for stitching. The toughness is further proven as it prevents puddles, rain, and other water sources from penetrating the fabric from the outside.
The interior features a single-layer eVent waterproof cleatie design that employs Direct Venting Technology, which is constructed from waterproof membranes. This technology keeps the foot dry while remaining breathable and durable. It lets moisture and vapor escape out through the fabric, thus cutting down the weight of the shoe.
The overlay structure of the upper is a series of 3D printed-on bands that keeps the foot in place especially during runs on rocky terrain.
An anatomical toe box presents an extra wide shape that presents plenty of room for a freedom of movement and a natural splay of the toes without being unsteady.
The laces are guided through ghillie loops that rest on a fully-gusseted tongue. The tongue is padded to allow flexibility, cushioning, and avoid hot spots in the midfoot area.
Rounding out the upper of the Hydroventure is a toe bumper that shapes the toe box. It protects the toes from injuries and enhances the fit.
