Ottobock Evanto Foot

Product Overview

The Ottobock Evanto Foot is a mechanical prosthetic foot for moderately active to very active users. It suits both transfemoral and transtibial amputees at Mobility Grade 2–4, with a maximum body weight of 275 lbs (125 kg). At a reference size of 26 cm, it has a compact build height of 82 mm and weighs about 450 g without the footshell. This low profile fits a wide range of socket and limb configurations while supporting confident movement across everyday New Mexico terrain.

Evanto pairs a carbon spring that uses a compact 3-point bending design with an ankle joint, connected so the pair can flex, twist, and move side to side. Together they mimic natural ankle motion for a smooth, lifelike walking feel. Its multi-axial flexibility and adaptation to uneven ground help users cover longer distances with less fatigue and move confidently in confined spaces, from Las Cruces sidewalks to gravel trails near Ruidoso.

Features and Benefits

• Exchangeable high-performance wedges: Swappable wedges tune energy storage, energy return, and shock absorption, giving customizable forefoot and heel behavior for each user.
• 3-point carbon spring: A compact 3-point bending design loads energy vertically through the ankle joint for a responsive rollover.
• Enhanced forward propulsion: In gait-lab analysis, Evanto showed up to 14% greater forward propulsion at toe-off for transtibial users and up to 19% for transfemoral users.
• Full multi-axial flexibility: Up to 20° of sagittal-plane motion, ±10° of medial-lateral flexibility, and ±4° of torsion keep the foot in contact with uneven terrain.
• Integrated shock absorption: High-performance wedges allow up to 24 mm of shock absorption at heel strike, plus up to 9 mm of vertical shock absorption when going down stairs or off curbs.
• Fully waterproof: Evanto can be worn in fresh, salt, and chlorinated water, with runoff channels on the adapter and drainage openings in the footshell.
• Anatomical footshell compatibility: Available in sizes 22–30 cm with slim and standard footshell options, offering excellent shoe-fitting versatility and everyday aesthetic integration.

Overall, the Ottobock Evanto brings together dynamic energy management, multi-axial adaptation, and full waterproofing in one compact module, representing the highest standard of Ottobock prosthetics and delivering dependable prosthetic foot performance that keeps pace with a busy lifestyle in Las Cruces, Albuquerque, and beyond.
