Built for fast and responsive urban skating

Echo Sonar 4 Freeskates were designed for city skating where quick reactions, stability and precise control matter the most. They handle sidewalks, bike paths, city streets and longer rides with confidence.

This model works great for beginner and intermediate riders looking for supportive urban skates with solid ankle support and comfortable fit. The shell shape also fits slightly wider feet well. Advanced skaters who prefer a very tight performance fit may consider sizing down.

Echo Flush Mount, direct power transfer

Echo Sonar 4 Freeskates use the Echo Flush Mount system, where the frame is mounted directly to the shell for a more connected feel.

The adjustable Y/I mounting system allows lateral positioning inside the shell, helping riders fine tune alignment and control. The result is quicker response, improved power transfer and more precise handling during urban skating.

Stable shell and comfortable liner

The hard shell made from reinforced PP composite provides support and stability during skating. The V-cut cuff improves flexibility and freedom of movement, while the 3 level cuff adjustment allows riders to customize the fit.

Inside, the liner combines neoprene, Lycra, EVA foam and polyester for comfort and support. The Hygge footbed, high density 2 mm TPE shock absorber and Echo X anti-slip patches help improve fit and stability during longer sessions.

CNC frame and urban 85A wheels

The one piece CNC frame delivers stiffness and precise control. Different frame lengths are used depending on skate size to maintain balanced handling and stability.

Sizes EU 36-42 come with 80 x 24 mm wheels, while EU 43-47 use larger 90 x 24 mm wheels for smoother rolling and better speed. The 85A wheel hardness offers a solid balance of grip, durability and urban performance.

For safer skating, it is always worth pairing your skates with a properly fitted helmet and reliable protective gear.

How to choose the right size

Measure your foot length in millimeters and compare it with the size chart below. Mondopoint refers to the actual foot length measurement. If you are between sizes and prefer more comfort, choose the larger size. Riders looking for a tighter performance fit may prefer the smaller option.
