When are shoecovers more than just a splash of style? When they're the Castelli Nano Shoecovers they are. Worn by the Cervelo Test Team, these ultra-lightweight shoecovers are made from Castelli's Nano material, a silicone-coated Lycra that keeps out chilling winds and light rain and road spray as well. Heavy-duty YKK zippers are used at the back for added durability, and silicone-coated elastics are used at the ankles for a snug, form fit for improved aerodynamics and to keep water from running down your leg and straight into your shoes.
The Castelli Nano Shoecovers come in Black and in five sizes from Small through XX-Large.
Keeps wind and water out with a pro look:

- Most overshoes are much of a muchness but the Nanos have a few features that set them apart from the crowd, and not just their Ann Summers looks. The lightweight, stretchy fabric is a much more supple than normal youre hardly aware youre wearing them and the polyurethane face is waterproof, unlike standard neoprene. Rain and spray can slowly soak in through the seam that joins the upper and lower sections its not taped but your feet will stay drier than normal in these. Even if water does get in, they still keep your feet reasonably warm, like most other overshoes.
- You dont get as much insulation as with thick neoprene, but the Nanos keep the wind off and allow your feet to heat up inside. Theres good coverage around the sole too with just small holes for your cleat and heel, and that makes a lot of difference. Weve found them about right for autumn use and milder winter days, swapping to something more hardcore when the mercury dips below about 7°C.
- You get a sturdy YKK zip at the back with a flap behind that stops it catching on your clothes or shoes, and reflective piping along the side makes a valuable safety feature. The cuff is elasticated to give a comfortable gap-free fit around your ankle while a silicone gripper is designed to hold the top in place not that weve ever had any issues on that score.
- As for the price, these are certainly among the more expensive overshoes out there but they do back that up with an impressive performance and the build-quality is high. Verdict: High-quality, water-resistant overshoes for autumn/spring and milder winter conditions.
I just got these yesterday, and finally can say I have found the perfect shoe cover! They are long enough to go a fair way up the ankle, and tight enough that water definitely wont trickle down the leg into the shoe; defeating the purpose of the shoe cover in the first place (in my opinion). These are tight, aero, and warm enough to ride in 9*C with wet roads. I got home and my shoe covers were dirty and wet on the outside, so I know that my nice new white shoes would have worn all that if it wasn't for the Nano Shoe Covers. Also, after returning home, seeing as the shoe covers were pretty dirty, I wiped them down with a towel, and since the material is very shiny, they look brand new again. I would highly recommend these to anyone who rides in the rain, wants to look after their shoes, and keep warm and dry. My shoes and socks were completely dry after the ride, and my clothes were all damp.
I wear size 44 Shimano shoes, and I got the XL Shoe Covers.
It says these keep your feet "warm, dry, and wind-cheatingly fast". Take out warm and dry. Even though they have the appearance of completely wind- and water-proof covers, my feet were soaking wet after riding in the rain. Haven't tested them in mid-season temps, but after a time trial hard ride in 34F weather, my toes were frozen. In addition, I have issues with their quality. The zippers don't always stay up (and they don't have a lock to ensure they do) and the material around the cleat opening started to tear from stretching after just 2 rides.
Nice concept, but maybe castelli needs to go back to Garmin-Cervelo test team for some fine tuning.
Let me start with fit. I wear a 44.5 and the Large seemed like it was going to burst at the seams, so i exchanged for Xlarge. XL is good, but not perfect - the heal and cleat cut out are probably designed for a 45.5-46.5, they work but could be closer for 44.5.
In the Narcissita, a Large fit me perfectly.
Zipper - this thing needs to be redesigned for such an expensive shoe cover. The zipper digs into your calf. you can do things to minimize this, but why should you have to on such an expensive cover? if the zipper was on the side, or maybe down zip with enclosed calf, or even some kind of cloth that covered the zipper top, it would be much better.
Pros- they fit the front and top of your shoe very well. I think they do very well in wind and temps in 40's. Probably be fine in high 30's with a very thick sock. I think they are good in wet stuff too - just not heavy rain..
Pro#2- they are very very packable compared to other shoe covers. You can wear them until it gets warm, then zip them off and put them in your jersey....most other over shoes i've tried, once you have them on, you'r committed for the entire ride because they are too bulky to take off. This is a real + if you live on the West coast.
Overall they could use a quality upgrade. other than the zipper issue they fit ad feel good. i doubt you could get more than a winter out of these as i suspect you'll tear a seam or puncture them with all the streching you need to do getting them over the cleat. and dont even think about cyclecross/ or anything that you have to walk much in...like coffee.
Would probably buy them again becaue the whole packability thing is +++ for me.
oh yeah, did i mention they look really cool?
