Sidi Hydro Gore winter boots

These Sidi Hydro Gore winter boots are really nicely made and comfortable, but they aren't the Italian shoe company's finest moment because they don't keep your feet dry, failing their primary mission objective quite severely.

As the name suggests, the Hydro Gore boots are made with a Gore-Tex membrane lining. This membrane is incorporated into a boot with no air vents to speak of, a carbon nylon sole with a regular three-hole cleat drilling and markings for easy cleat alignment. The heel is reinforced and there are four Velcro straps to keep the boot secure on the foot.

Fit is really good, with ample space for a pair of thicker merino wool socks. The four Velcro closures do an adequate job at clamping the shoe in place, but it's odd not to see a more advanced closure mechanism given the high price. But the fit is good enough that you don't need much pressure with the straps, and the heel cup hugs the back of the foot well, so Sidi is forgiven here.

The Gore-Tex lining does a sterling job of stopping water from entering the foot section, especially around the front where it can be subjected to constant spray generated by the front wheel. In that respect they're more robust to repeated spray than overshoes and regular road shoes, especially if you ride without mudguards.

They're a warm shoe, too. When it's cold and dry these shoes kept my feet warmer than even the best overshoes I've tested, with nowhere for the air to leak in. The breathability is sufficient that I didn't suffer any unduly sweaty feet, even on warmer rides when a winter boot is probably overkill.

Unfortunately, the boots failed to keep water out in properly heavy rain. On closer inspection it's obvious why this is happening: the neoprene closure has been designed in such a way as to prevent any restriction around the ankles when pedalling, but unfortunately it does mean there's a big old gap for water to dive straight in. You can cinch the large Velcro strap up, but there's still a gap when pedalling, plus they are then uncomfortable around the ankles.

It's a real shame, because I had high hopes for these winter boots, but as they are it's hard to recommend them for wet weather riding (they're fine in the cold and dry). Your money is better invested in some really good overshoes worn over your regular cycling shoes.

Designing a winter boot that is completely waterproof without compromising fit and comfort is a tricky challenge, and one that few shoe manufacturers have really nailed yet. If Sidi can improve the neoprene ankle, it's on to a winner.

Verdict

Good in the cold, pretty useless in the rain
