Measure your foot length before ordering. To select the correct size: add 5mm to your measured foot length, then refer to the corresponding EU size. 2、Unique Device ID: Each pair of shoes comes with a unique ID (the Bluetooth device number printed on the hang tag). Please keep it in a safe place—loss of this ID will prevent Bluetooth connection to the device. 3、First-Time Activation: For optimal performance, charge the wireless EMS pulse device to activate it before first use, then pair it with your smartphone via Bluetooth. 4、Module Handling: Before installing or removing the wireless EMS electronic module, read the user manual. Never pull the electrode pad area directly to remove the module—this will damage the device. 5、Usage Safety: The massage function is recommended for stationary use only. Do NOT activate it while walking, running, or driving, as it may impair nerve responsiveness and cause accidents. 6、Daily Usage Limit: Do not use the wireless EMS pulse system for more than 2 hours total per day. Multiple short sessions are recommended over prolonged continuous use. 7、Cleaning Instructions: Do NOT wash or soak the shoes in water. Always remove the wireless EMS electronic module before cleaning. Allow shoes to air-dry completely before reinstalling the module. 8、Insole Care: Do NOT scrub the conductive fabric on the insole. For cleaning, gently wipe the surface with a mild detergent and a soft cloth. 9、Battery Maintenance: If the wireless EMS electronic module will not be used for an extended period, recharge it every 1–2 months to maintain battery health and extend its lifespan. 10、Start Slow: Begin at the lowest intensity level when using the device for the first time. High-intensity settings may cause discomfort if your body is not acclimated.
