New to the smart tech market is the advent of smart fitness socks. Sensoria Fitness Smart Socks are a type of wearable tech that can help runners improve their performance.

The unique socks are made with undetectable proprietary textile sensors that record distance covered, measurement of pace, calories burned, and information regarding foot strike.

Able to inform runners of the specifics of foot-to-pavement moments, they also measure heart rate, ascent and descent, cadence, number of steps, and altitude gain. Because users can connect their footwear type to Sensoria’s database, analytics can be even more accurate than similar devices.

Data is collected via a Bluetooth-enabled anklet that attaches easily to the top of a sock cuff. Users can access data through the Sensoria mobile app made for both iPhone and Android.

If you’re worried about keeping your smart socks clean, don’t fret. They’re proven to still perform after 60 machine-washings. Four pairs of socks used an average of four times a week are projected to last about a year.

Interested customers can get their starter package for $199.
