- Size Before You Buy: To ensure the best comfort and performance, we strongly recommend using the BOYACARE Sizing Kit before placing your order. Please note that this sizing kit is designed specifically for this product and is not compatible with standard rings
- Non-Standard Sizing: This product features built-in sensors on the inner surface, resulting in a fit that differs from traditional rings. The sizing kit helps determine the most accurate size to ensure both comfort and proper sensor contact. Available sizes range from 6 to 13
- How to Measure: Select one or several sizing gauges and wear them to find your ideal fit. The correct size should feel snug yet comfortable. For best results, wear the selected size for up to 24 hours to confirm it remains comfortable throughout daily activities
- Choose a Finger: The ring can be worn on any finger of either hand. For optimal comfort and tracking accuracy, we recommend the index, middle, or ring finger. Be sure to measure the exact finger you plan to wear it on for the most accurate fit
- Sizing Made Simple: The BOYACARE Sizing Kit helps eliminate guesswork, reduces incorrect sizing, and helps prevent unnecessary returns. It’s ideal whether you’re purchasing for personal use or selecting the right size for a thoughtful gift
