Description
Unleash next-level insights with the Reebok Smart Ring. Sleek, subtle, and engineered for performance. This wearable fitness, health, and wellness tracker turns complex biometric data into one simple, powerful number—your One Score.
Ordering a ring sizing kit will help you select a size that ensures optimal accuracy and comfort day and night.
Your ring should fit snug and secure on your finger, but not to the point where it's uncomfortable. Try making a fist to ensure there are no gaps between the ring and the finger. Wear the sizing ring with the size number visible on top of the hand.
Take your time to find the perfect fit, we recommend wearing your sizing ring for at least 24 hours before confirming your size. You will receive via email a $10 coupon to go toward your ring purchase upon delivery of the sizing kit.
The sizing kit is final sale and may not be returned. View return policy.
