Two years ago Spanish shoe maker Luck announced its prototype power meter that is built into cycling shoe soles. At Eurobike this year, Luck has a finished product that the company is selling for €200 per shoe.
The Luck Potentiometer (power meter) can be bolted onto any high-end Luck shoe — road or mountain — according to Luck director Juan José Pascual. There are about 16 models for between €200 and €300 that can use the meter. US and UK pricing was not available.
While the prototype was Bluetooth only, the new version is Bluetooth and ANT+, so it can work with the company's app or any standard cycling computer like a Garmin Edge.
If you use one meter on one shoe, it operates like a Stages or 4iiii one-sided crank-based meter — it just doubled the wattage number for a single power figure. If you buy two, then you get left/right power as well.
Luck also offers a range of custom options, inside and out of the shoe. You can buy custom-fit shoes based on your measurements, and custom-printed designs are available, too.
Some of the Luck shoes have leather uppers, and the high-end mountain shoes feature natural rubber lugs.
