Wear the type of socks you'll wear with your shoes and measure feet in the afternoon (feet typically swell during the day). Distribute weight evenly before measuring.
Good result, but eye. Although the pedals are spectacular, as in a Model 3 Performance, the footrest cover is not suitable for Model 2021, or at least for mine of May 2021. The reason is that he wears a smooth carpet and not a piece with the rubber striations where he fits the piece. Besides, the new carpet would cover it. Better buy only pedals.
