TECHNICAL FEATURES
Feel in complete control as you revolutionise the way you train with the O+A Reflex Performance Calf Support. Designed by sports scientists and anatomically engineered to help you dominate every session, our leggings feature our patented Neuromuscular Performance System with flexible skeleton structures that proactively stabilise your calf muscles during activity. Fatigue is diminished as you feel confident and perform at your best, even as you push yourself to the limit - and beyond.
The Performance Calf Support incorporates 3 sensory nodes at the proximal and distal superficial calf muscle. By interacting with the skin these nodes stimulate tactile mechanoreceptors and amplify afferent feedback to the nervous system, tapping into your own innate sense of proprioception to help you maintain full awareness of your running form throughout each session. Feel empowered with the ability to improve muscle recruitment patterns and facilitate efficient activation with every step you take.
Push your boundaries as you say goodbye to lacklustre sessions and hello to your best performance yet. Strong performance compression over the calf muscles reduces vibration during running or high-impact activity, streamlining feedback to your nervous system and decreasing the activation required for damping. You'll be able to train more efficiently, reducing fatigue and damage, and with fast recovery, ensure you're ready to go day after day.
Screen-printed silicone cuffs provide a close but comfortable fit, with no slippage whatever activity you throw at them.
TARGET MUSCLE GROUPS + JOINTS
Designed specifically with your calves in mind, our calf support is crafted to help you smash your run each and every time.
TARGETED SUPPORT
Y-shaped skeleton structures stabilise the superficial calf for improved muscular control.
MOVEMENT CONSCIOUSNESS
3 sensory nodes interact with skin over the calves, enhancing proprioceptive feedback to facilitate dynamic muscle activation.
MUSCLE-MAPPED COMPRESSION
Muscle-mapped compression over the calves works to reduce muscle vibration and support efficient contraction.
THERMAL REGULATION
Moisture-wicking fabrics help control temperature and keep you feeling dry through every session.


Engineered moisture management and breathability draws sweat away from your skin to keep you feeling dry.

Nylon Tactel™ has a premium soft feel that is gentle on the skin and dries quickly.

A tight body-hugging fit to provide performance-level compression and minimise muscle vibration.

Silicone cuffs keep the garment and flexible skeleton support in position as you train.

Sensory nodes interact with the skin to maximise proprioceptive feedback and promote efficient movement.

Anatomically positioned flexible skeleton structures support and stabilise the body during movement.


fit and care
1. Start by placing your thumbs inside the top opening of the calf support, and gather up the rest using your fingers.
2. Place your foot through the gathered support and unfold up your leg. DO NOT forcefully pull the garment from the top as this will risk tearing.
3. Align the skeleton along the natural path of your calf muscles, accurately positioning the sensory nodes as per the graphic.
