In the drudgery of winter, the improvisers freeze while the well-prepared flourish -- believe us, at 7000 feet, we know a thing or two about harsh weather. So, if you intend to ride all year, you'll need to make a choice. Hopefully, you chose the latter, and accordingly, you'll need the Castelli Diluvio Shoe Covers 16. With a warming, water-resistant design, the Diluvio covers will keep the chill off of your feet, and help keep you in the saddle with the roads all to yourself.
Castelli's Diluvio ShoeCovers feature a 3mm-thick, neoprene construction. This stretchy, dense material protects against both the cold and moisture. In fact, Castelli estimates the Diluvio's effective temperature-range to be between 23 and 53 degrees Fahrenheit. For water-resistance, Castelli thermosealed all of the seams. This process is devoid of stitching, so even the most minute of apertures have been eliminated to prevent leaking. Further along these lines, the Diluvio has a Velcro closure-system over the 16mm cuff that seals off the foot from any water running down the legs. The Velcro also makes it a breeze to get your shoes in and out of the covers. And for when you're out of the saddle, the covers have been left open around the cleat and heal. So, you never have to worry about tearing up the soles when you're walking from A to B.
The Castelli Diluvio Shoe Covers 16 are available in the color Black and in the sizes Small/Medium, Large/X-Large, and X-Large.
a bit of a battle to get over the velcro elements of your shoe, but ultimately they keep your feet quite warm. with just one pair of wool socks and these on, my feet are not at all cold in temperatures as low as the 30s. will update review once weather permits me to try them at lower temperatures.
the material is simply neoprane, nothing fancy. it blocks wind and soaks up water but still insulates. when i remove them after a ride, they are usually moist with sweat but with no detriment to my warmth.
best features: zip up rear, reinforced ankle (superior to diluvio non-16 which lacks any reinforcement there and is likely to split up the backside the first time you pull it on), large reflective strip going up entire back of boot, warmth & windblocking, blocks middle vent on sole of shoe between cleat and heel pads
cons: on-off is a little violent due to the lack of any sort of smooth inside surface (it's just one noeprane membrane). i sometimes think it won't last more than a season. but only time will tell
sizing: castelli's size recommendations worked (size 43 real shoe, order L/XL and it's very right)
overall: buy if you want to stop shopping around for winter covers and just be warm
Been using the Diluvio 16 shoecover on dry rides ranging 36-48 degrees and they are awesome. Very comfortable & warm. I think 50 degrees is the top of the range. As some have noted, you'll probably get a little sweaty inside but not cold. I don't find this to be a problem. I bought the 2XL and they fit my Sidi 45.5 like a glove so I guess that means size up! I don't find them hard to get on and off at all. As expected with a wetsuit-like fit, it does require a bit of care in stretching them on, but it's really no hassle.
These are fantastic shoe covers. A size L/XL fits my 43.5 Specialized shoes great. Not too tight, not too loose. So far, I've worn them in temps ranging from 35-55F, and they are great all throughout that range. They do get a bit damp from sweat on the high end of that range, but I never noticed until the end of the ride when I took them off. Feet have never been cold with these on and they block out the wind great! If you want warm feet on chilly rides, just get these. Plus, they look rad.
These shoe covers work well in 10-42 degree weather. Ventilation is not the best so your feet could get sweaty but the shoe cover will do a good job keeping your feet warm. I wear a 42.5 shoe and the S/M is tight but works. I would recommend the Diluvio shoe cover 16 for cold weather rides.
Really nice shoe covers. Warm. Can always be paired with neoprene socks for that extra level of protection from the cold. However, when it is that cold you might as well hit the indoor trainer up. Unless you like your balls in your stomach. Just sayin'.
I got the sm/med for my size 41 road shoes and that is probably as big as you could go. zipping up the ankle is also a challenge even for my skinny legs. snowed here, so a warmth review will have to wait.
EZ on EZ off kept toes toasty at around 35 degrees for 2 hours, size 11 shoes went with XXL.
The l/xl fits about a 45 shoe
After riding 2 hours in a 30 / f. weather my toes were frozen, i will try side's hydro gtx next. I'm truly convinced that booties do not work for cold weather.
