Ready for the deluge.

When it's really coming down — and especially when it's really cold out — the taller cuff of a shoe cover can be the difference between a happy ride and a crappy ride. The Castelli Diluvio 16 Shoe Covers have 16cm cuffs, and their three millimeter-thick neoprene has thermosealed seams to block water, with cleat and heel cut-outs below to make walking a little easier. Reflective details make you more visible after the sun goes down on those short winter days, too.

Good for winter riding and training

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I've used these shoe covers all last winter, and for the first half of this winter. I commute daily, and also am a road bike racer - they have served well for all my needs, and I would recommend them. You can see my full review with photos here:

Benchmark winter booties

    Castelli is based in the foothills of the Italian Alps (Dolomites); they know Winter cycling.

    These booties are GREAT for cold weather cycling and will keep your feet warm down to about 30/35° F with bibtights and quality wool socks -like Castelli's Quindici socks.

    PROS: The 16 cm height is to keep the rain out (and for looks). Neoprene is very water-resistant and the central seam is thermosealed (nice). These also feature a waterproof zipper and zipper garage (nice). The zipper garage keeps the zipper from flopping up & down on each pedal stroke (and from snagging on your tights). Hi-viz strip down back.

    CONS: On really long, wet rides, these will eventually soak through.

    Tip #1 for riding in the rain: If you need total rain resistance wear Velotoze over these.

    Tip #2 for riding in the rain: Water spray from the front wheel can work its way up through the vent holes in the bottom of road shoes (if your shoes have them). Tape those up with duct tape on wet days or your socks will get soaked from the bottom.

    Tip #3 for riding in the rain: During dry cold rides, everyone tucks their bibtights (leg) into their booties of course. On long rainy rides, however, I recommend trying wearing your bibtights -over- your booties. Otherwise rain will eventually seep down your bibtight fabric to your socks and soak your feet. Yuck.

    Diluvio sizing:
    36-40: SM/MD
    41-40: L/XL
    45-48: XXL
    These are benchmark and Castelli's best winter booty value.


    • Familiarity: I've put it through the wringer

    The Diluvio 16's are nice and tall shoe covers that provide plenty of warmth in freezing weather. They also keep the rain out in soggy conditions. The only downside, they do not breath extremely well. So your feet may be a bit sweaty at the end of your ride.

    Castelli Diluvio 16 shoe covers

    • Familiarity: I've used it several times

    Had high hopes for these shoe covers. After about 5-7 rides wear holes appeared in the base of the shoe covers which have continued to get bigger with each subsequent use. Very disappointed in the build quality of this product and had hoped for better from Castelli. At least they look good

    Tore hole in nose

    • Familiarity: I've used it once or twice and have initial impressions

    Size chart lists L and XL bit pruduct comes L/XL. I wear sixe 11 so it should have fit even though on the outer limit. Exchangingfor XXL. Last pair was great but stolen via car break in.

    what temp range is this rated for?

    Castelli rates the Diluvio 16 winter booties for use in 32 to 55* F weather. Wear good wool socks in colder weather.
