LONO Shoe Sizing

LONO Shoe Sizing app makes finding your barefoot size measurement quick and simple. Designed specifically for barefoot and minimalist footwear readings, our app helps you find the optimal measurements without the guesswork.

Choose the measurement method that fits your device:

• LiDAR Scan (iPhone Pro Models): Uses your device's built-in LiDAR sensor to measure your feet quickly and accurately using nothing more than a wall. No paper sheets, credit cards, or rulers required.

• A4 Paper Scan (All iPhone Models): Simply place your foot on a standard A4 sheet of paper against a wall, and our camera system will use it as a precise sizing reference.

Why Choose LONO Shoe Sizing app?
• Brand-Neutral Millimetre Precision: This brand-neutral measurement empowers you to accurately check size charts across any shoe brand you choose.
• Consistent Results: Multiple measurements are combined to improve accuracy and minimize human error.

Device Requirements & Privacy:
• LiDAR Mode requires an iPhone Pro model with a LiDAR sensor (iPhone 12 Pro or newer).
• A4 Paper Mode is fully compatible with all iPhone models running iOS 18.5 or higher.
• Privacy & Data Control: LONO Shoe Sizing app uses your camera and LiDAR sensors exclusively for local foot measurement calculations. No raw camera images or depth scans are ever stored or uploaded. If you optionally choose to email your final sizing results to yourself, we will securely retain your size measurements and associated email address solely to deliver your report. Otherwise, no personal data is collected.
