Spatz Aquasokz Hi – Waterproof Aerodynamic Cycling Oversocks

The Spatz Aquasokz Hi are premium aerodynamic cycling oversocks developed for riders who demand maximum speed and performance in challenging weather conditions. Designed specifically for the Alpecin-Deceuninck Pro Cycling Team, these innovative aero oversocks combine advanced aerodynamics, waterproof materials, and a race-focused fit.

Proven at the highest level of professional cycling, the Spatz Aquasokz Hi were worn by Mathieu van der Poel during his victory on Stage 2 of the 2025 Tour de France. Engineered for WorldTour racing, they are designed to help cyclists maintain aerodynamic efficiency even when the weather turns wet and unpredictable.

WorldTour-Proven Aerodynamic Performance

The Spatz Aquasokz Hi were developed in close collaboration with the Alpecin-Deceuninck Pro Cycling Team, with one clear objective: create a high-performance aerodynamic oversock specifically optimized for wet racing conditions.

Every detail has been designed with speed in mind. The close-fitting construction creates a smooth transition between the cycling shoe and lower leg, helping minimize aerodynamic drag.

Whether you're competing in road races, time trials, criteriums, or fast training sessions, the Aquasokz Hi offer professional-level aerodynamic performance.

Wind-Tunnel Tested at Silverstone

Aerodynamics play a crucial role in modern cycling, and the Spatz Aquasokz Hi have been extensively tested at the Silverstone Sports Engineering Hub wind tunnel.

Testing demonstrated significant aerodynamic improvements across nearly all yaw angles compared to an oversock with a similar silhouette.

This optimized aerodynamic profile makes the Aquasokz Hi an excellent choice for cyclists looking to reduce drag and maximize efficiency, particularly during high-speed efforts and racing.

100% Waterproof PU-Coated Lycra

The Spatz Aquasokz Hi are constructed from 100% waterproof PU-coated Lycra, combining a smooth aerodynamic surface with excellent flexibility and a close-fitting design.

Unlike traditional winter cycling overshoes, the Aquasokz Hi prioritize aerodynamic performance rather than complete foot insulation or waterproof sealing.

Although the material itself is waterproof, the oversocks are not specifically designed to keep your feet completely dry. Instead, they provide an aerodynamic outer layer that performs exceptionally well in wet and demanding conditions.

The lightweight, flexible construction ensures that riders can maintain a streamlined fit without unnecessary bulk.

Race-Focused High-Cut Design

The Aquasokz Hi feature an extended high-cut design, creating a smooth aerodynamic transition from the cycling shoe to the lower leg.

The close-fitting ankle and leg construction minimizes excess material and helps maintain a streamlined silhouette during intense racing efforts.

Compared to the lower-cut Aquasokz Lo, the Hi version provides additional lower-leg coverage for riders who prefer a taller aerodynamic oversock.

Precision Fit for Maximum Aerodynamic Efficiency

The Spatz Aquasokz Hi are specialist racing oversocks designed to fit extremely close to the cycling shoe, ankle, and lower leg.

To achieve optimal aerodynamic performance, the ankle section is deliberately tighter than that of the Spatz Windsokz.

This close-fitting construction can make the oversocks slightly more difficult to put on during the first few uses. However, the material gradually becomes more supple, making installation easier over time.

Important fitting advice: Always roll the Aquasokz Hi up your lower legs before putting on your cycling shoes. Once your shoes are on, pull the oversocks down over them to achieve a smooth and secure fit.

Spatz Aquasokz Hi vs. Aquasokz Lo

The Spatz Aquasokz range is available in two versions: Aquasokz Hi and Aquasokz Lo.

Both models feature waterproof PU-coated Lycra and are designed to provide aerodynamic performance in challenging weather conditions.

The main difference is the height of the oversock.

The Aquasokz Hi feature a taller construction that extends further up the lower leg, while the Aquasokz Lo offer a shorter profile.

The Hi version is ideal for riders looking for extended aerodynamic coverage and a sleek, professional racing appearance.
