Light shoes or grip socks are the better choice for most users — they protect joints from high-frequency impact while keeping enough vibration transfer for effective muscle activation on a vibration plate.
Using a vibration plate completely barefoot transmits the full oscillation directly through the foot's bones and joints, which some users tolerate fine at lower speeds but find uncomfortable or fatiguing at higher intensity levels. At EvoSpark's upper speed range (60–120), the rapid plate movement can create joint stress in the ankles and knees without the cushioning a thin-soled shoe provides. That said, barefoot use at speeds 1–20 is reasonable and enhances the acupressure surface contact on EvoSpark platforms.
- EvoSpark speed levels 1–20: barefoot use is generally comfortable and maximizes acupressure surface contact.
- EvoSpark speed levels 60–120: thin-soled shoes or grip socks recommended to reduce direct joint impact.
- EvoSpark platform acupressure surface: raised texture designed to stimulate pressure points during barefoot or sock-only sessions.
- Grip socks add traction without blocking vibration transfer — a practical middle ground on EvoSpark's anti-slip deck surface.
