Smart Sandals That
Guide You Home

You're 3 hours into a desert hike, your sandals gently vibrate and whisper 'shade available in 200 yards, northeast'—you follow the direction and stumble upon a hidden rock overhang exactly where predicted. Later, as you push too hard in 105°F heat, the sandals alert you 'heart rate elevated + terrain difficulty increased + no shade for 2 miles—recommend 15-minute rest now.' You sit, drink water, avoid heat stroke that would have struck you 20 minutes later.
