If your priority is maximum power, and if you’re not likely to be training for long periods of time, then why not splurge? However we’ve made an exception for these because the breathability and ventilation they offer is second to none, and the sock-like comfort that comes with wearing them means they’ve made the list anyway. Technically the Empire E70 Knit shoes from Giro were not developed specifically for indoor cycling, and they have a carbon sole which is something we have advised against in our guide below. One of our male testers has reviewed the men's version of the Giro Regime Road shoes, and many of the features are shared across the genders, so take a read for more in-depth detail. If you're looking to maximise your power output during your Zwift sessions, you can't go wrong with these. Meanwhile, the carbon composite sole offers impressive stiffness that refuses to flex even during out-of-the-saddle stomping on the pedals. What's more, it contains perforations across more than half its exterior in order to facilitate airflow for decent cooling. All this is to say that the single-piece upper provides superior structure and stability devoid of the potential for hotspots or discomfort. It features the brand's innovative Synchwire technology, a thermal-laminated TPU with supple and breathable monofilament mesh. Featuring trickle-down technology from Giro's Imperial road shoe, the Women's Regime Road is designed to eke out every single watt from each pedal stroke.
