Item # CST2485

Hot foot is more than just a dance.

Balmy shoe covers aren't for everyone, especially when the weather doesn't warrant it. When the roads are wet, but the skies are clear, strapping on a full bootie is a recipe for hot, sweaty feet. That's why Castelli made the Toe Thingy. The Toe Thingy lets your feet breathe while protecting the front of the foot from water and wind. 

Castelli's Toe Thingy is made from durable neoprene fabric. This material not only provides insulating warmth, but it also blocks water and wind on the most sensitive part of the foot—the toes. The Toe Thingy is secured to the shoe by an aperture that encompasses the cleat, and to resist rips, tears, and general wear, Castelli included a silicone print on the Toe Thingy's underside. For versatility, Castelli recommends using the cover alone on mild days, and as a layer between your shoe and full shoe cover during nasty weather.

The Castelli Toe Thingy is available in one size, and in the color Black.

Works surprisingly well in heat as well!

  • Familiarity: I've used it several times
  • Fit: True to size
  • Height: 5' 8"
    Weight: 145 lbs

It appears that many reviews so far glow about how well these thingies keep feet warm in 30°-60°F weather. My review is a bit different in that I live in Florida, so while I have to deal with rain & wetness all the time, I also have to deal with the ungodly heat. Surprisingly, these foot thingies do not overheat my feet or cause excess sweat, even in 90°-100°F weather! That's probably because they're so breathable and aren't full coverage.

Now unfortunately they don't keep my socks completely dry in the rain, again because they aren't full coverage (my upper sock and ankle area get wet). That said, they do protect my feet & socks quite well from early morning dew/mist and after-rain puddles & humidity. They completely cover the mesh breathing port at the front of my shoes just under my toes, preventing any water or condensation from reaching my socks...and again, because they aren't full coverage, they still allow me feet to breathe.

They fit incredibly well for a one-size-fits-all item...they aren't too big to feel loose by any means, and yet they aren't so small that they are difficult to get on or off...they are perfectly snug on my shoes. I've used them several times now, but have only had them for a few I can't comment on their longevity. Hopefully the build quality is superior...even if it isn't, I wouldn't hesitate to buy another pair at this incredibly reasonable price point.

Toasty Toes

  • Familiarity: I've put it through the wringer

I've been using these for about two months now and pretty much bring them on all of my rides. for those cool misty morning rides they're great for keeping your toes the perfect temperature, and when it starts to warm up during the day, they still let your feet breath as they only cover abount halfway up your foot. I have tried them in the wet, and they soak up a lot of water as was expected. If it's wet these make a great insulting layer under your rain booties!

Surprisingly durable thingy

  • Familiarity: I've used it several times

I've never had much luck with foot thingies, but this thingy is a Quality item. Easy to get on and off, but the thingy stays on snug. What's most surprising is that the thingy hasn't ripped or become damaged coming on and off the shoe a few times a week. I've had these thingies several months now.

sweet thingy

These are great - easy to slip on and off and sole opening fits nicely with my look cleats.

Castelli toe thingy

  • Familiarity: I've used it several times

These light, half shoe covers are perfect for the chilly morning rides. I've used other brands, which were hard to put on and didn't fit right. The Castelli covers, with their stretch material, fit great and they look great also!

does it's job

  • Familiarity: I've used it several times

I've paired these toe thingy's with different types of wool socks for cold days in the 40s and 50s and it has done well. Blocks the wind nicely and seems to stay in position on the shoe well. No complaints, hopefully it holds up for a while.

Great for those in-between temperatures

  • Gender: Male
  • Familiarity: I've used it several times

I never thought I had a need for these but was in a buy-happy mood on Black Friday and decided to give these a shot. The first ride with these, it was 47°F and pretty calm. I used them with the Castelli Gregge wool socks and they were incredible. Feet never got cold or hot. Before, I only had thick Pearl Izumi winter booties, and those aren't really necessary unless it's under 45 degrees or so. These toe thingies are great for temperatures between 45-60°F. I would recommend them to anyone riding in these temperatures. They'll certainly be serving me well for years to come.

Nice accessory!

  • Familiarity: I've used it several times

Threw these on when the temps are 50-60's to keep the breeze off my toes and they do a good job. With wool socks they will save frozen toes. Like mentioned before, very easy to put on and take off. Seem to be good quality and are a nice in between instead my full shoe covers for cool days. For $20, everybody should have a pair!

So simple and so great!

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

I purchased these in lieu of full shoe covers for a couple of reasons.
1. I had read that shoe covers can get too warm, and I hate sweaty feet.
2, The reviews below recommended them.

I haven't ridden in cool temps for many years, and recalled that it was not a pleasant experience. Since then, I have come to recognize and appreciate the value of having the right gear for the time of year.

These toe thingys are a great example of the right gear. I wore them yesterday for a ride in a brisk 41 degrees, and I actually marveled at my foot comfort. Warm, not hot toes, and a nice temp for the rest of my feet. To be fair, I also wore medium weight wool socks (not wanting to take any chances).

They are super easy to put on, and they look great. I'll just leave them on my shoes until it gets too cold and I'll get booties.

Based on my comfort factor at 41 degrees, I suspect these will be good into the low 30s (definitely wool socks, then).

So simple and so great!

Cozy Toes

  • Familiarity: I've used it several times
  • Fit: True to size

I got these when I bought a pair of triathlon shoes with no tongue which was leaving the tops of my feet exposed. They do a good job of keeping my feet warmer on cool fall and spring days 50's to 60's. For really cold days I go with a pair of full neoprene shoe covers.

Great for their purpose

  • Familiarity: I've put it through the wringer

Been using these for a little more than a year in a variety of temps and they are great. I would say their effective range is low 40s to high 50s (maybe lower with a good pair of winter socks). They do exactly what you need them to do -- block the wind and take the edge off those chilly (not subzero) rides. Rode with them on in the high 30s the other day and the chill was a little much when starting out. Simple on/off but I just leave them on for most of the fall. Strongly recommend these as transitional weather shoe covers. Be warned, if you are looking for COLD weather covers, these are not the call.

For those of us who are cheap :)

If you go hardcore into cycling, you realize the value of all the specialized bits of apparel. There are shoe covers for every occasion: speed, rain, cold, and cold and rain. The good ones, alas, don't come cheap. But there are alternatives that, while not necessarily ideal for all conditions, can help. That's where the toe thingy comes in.

If the road is wet or you're riding in a drizzle it'll do a good job keeping the leading edge of your foot dry, which is where you really feel the discomfort. The warming benefits seem to me to be fairly minimal given the amount of ventilation that my cycling shoe has, but the toe thingy delays the onset of cold feet a fair bit in temps down to the 40s (but really these are designed for milder temps). Where the toe thingy really shines is convenience. Unlike your typical shoe cover, it's a cinch to put on and you won't wear out any zippers or tear the neoprene on the ground walking around. Plus it doesn't cost much!
