The Giro Alpineduro boots use the same grippy Vibram sole that can be found on Giro’s Terraduro trail shoes, and have retro hiking looks that would suit any lumbersexual.
We found the boots to be warm, even on brutally cold days, but the soles aren’t as aggressive as we’d like for mountain biking, particularly in the UK’s typically muddy conditions. The laces, of course, are a matter of personal preference; our testers were split on this. The design looks great to some, but the laces get mucky quickly and aren’t as easy to clean as a traditional shoe with Velcro straps or ratcheting buckles.
The microfibre upper is highly water-resistant and breathable. It’s lined with PrimaLoft insulation, with a bellow tongue to keep the worst of the weather out. Rubber reinforcement around the toe and heel increases support while adding protection. The rear of the boot dips around the Achilles tendon to offer a good range of movement.

The Alpineduros are easy to hike and pedal in, and are generally quite warm
The SPD-compatible Vibram sole is made from soft compound rubber and has been specifically designed to give good grip on wet, slippery surfaces. It works well off the bike on firm ground, such as traffic stops on rainy commutes. But a slightly more aggressive tread design at the toe would help the Alpineduros’ performance in muddy conditions on mountain bike riders.
The sole is flexible enough at the toe for easy hiking, but still firm through the arch and heel for a solid pedaling platform.
Our size 45 test sample weighs 555g per boot. It’s worth noting that the boots run slightly small, especially through the toebox. As loft is often a key factor in warmth, we’d suggest going up at least half a size.
Bottom line? The Giro Alpineduros are perfectly functional for mountain biking, but might be better suited for foul-weather commuting.
