The ESP Aegis SoFlex Liner is a soft, lightweight prosthetic interface designed by ESP for transtibial (below-knee) and upper-extremity amputees.

• Material: 100% health-grade silicone with a durable fabric cover.
• Thickness: 3 mm thick profile.
• Pre-Flexed Design: Pre-flexed at 45° to emulate a bent knee, improving comfort and allowing an unrestricted range of motion while reducing bunching or creasing when sitting or standing.
• Suspension Options: Available in both Locking (with a flexible shuttle umbrella) and Cushion (non-locking) versions. The locking variant utilizes engineered lockstitch technology to help minimize pistoning (unwanted vertical movement of the limb inside the socket). Flexible Shuttle Umbrella in Locking Liners.
• Activity Levels: Suited for K1 through K4 activity levels, and compatible with standard suction suspension or shuttle lock socket systems.
