Choose between the GORE Bike Wear regular and thermo Race Power II Shoe Covers. Or just get both pairs. The Gore-Tex Performance Shell blocks moisture without sealing your shoe and foot in air-tight stuffiness, while abrasion-resistant material at the sole increases this shoe cover’s durability. Cut-outs accommodate both your pedal system and the heel of your shoe, while an adjustable hook-and-loop system and neoprene stretch shaft top provide a snug, aerodynamic fit. The thermo shoe cover has a warm fleece backing for chilly races.

More sizing info

    Just adding to the sizing data, since I wasn't sure when I was ordering: the size Large (labled by Gore as "9.0-10.5" and "EUR 42-44") just barely fits over a Pearl Izumi X-Alp Seek IV size 45 (US 11.5), a MTB/commuter type shoe. My first thought when I started pulling them on was that I would need an XL, but it covers the shoe and the velcro meets in the back ok, so I think I will stick with the Large.

    For my SIDI Dominator IVs (which unfortunately aren't marked, but must be either a 44 or 45), a lower-volume "cycling" shoe, the size Large also will work, but is a little on the loose side. I would guess that a Medium might work for those as well, perhaps better.


    Wish these worked better...

      I'm afraid these aren't the answer to dry feet I was looking for. I've been riding them for several months and haven't had as much success as other reviewers. Went for a 2 1/2 ride yesterday in light- to medium heavy rain & mid 40's temps here in Seattle.. At the end, my feet were quite wet, which has been the case most of the times I've worn these in the rain. I believe much of this wetness came in through the neoprene at the top of the overshoe.

      In addition, I've found that the reinforced hem around the cleat hole on the bottom of the shoe is a little thick. If I don't pay attention, using my Shimano cleats, this hem can get underneath the front of the cleat and make it difficult to clip in.

      I concur with the advice to the double-check the sizing. I wear a 43.5 in a Sidi (Genius 6.6), and I purchased a size L. The label inside the overshoe says L - 42-44.

      Finally, a solution for cold, wet feet

        Tried many different shoe covers, from neoprene to Amfib to rubber-coated and so on. Then went with Northwave hi-top winter shoes, and still no satisfaction. Finally took a chance on these Gore Race Power (Thermo) overshoes, and couldn't be happier. These are to the feet what BarMitts are to the hands for winter riding, though quite a bit more svelte. These do not run large...on the contrary, I could not fit a Large on my size 44 shoe, so had to size up to XL. Those fit great. I've ridden many, many winter miles this year through rain, slush, bitter cold, wind and precious little sun...the Gore Race Power (Thermo) kept my mind completely off my feet because they were simply warm. Warm! What else do you need? They even protect you at that little point on the top of your foot where the ankle flexes upward, and water always seems to find a way in...not the case with these. I pull them off and the only moisture is from foot sweat, because again, the feet are warm. These covers + my regular road shoes + DeFeet WoolEator socks are all I need to get me through winter. Good stuff

        Unanswered Question

        I am actually looking at these to put over sneakers for winter snow shoe racing, has anyone ever purchased for this use. Just wondering how they would fit over running shoes vs bike shoes.
        Also , what is sizing for Women 8.5? a small or medium? previous posts said they ran a little large. Any help would be appreciated.

        I'm buying them as a gift for a man who...

        I'm buying them as a gift for a man who wears a size 12M. XL? And they go over clip cycling shoes, right?

        Hi Erin,

        Definitely go with the XL. and yes they'll fit the shoe type that clip into the pedals.

        hope that helps,

        What is the height of the overshoe measured...

        What is the height of the overshoe measured along the back, from the heel to the top which wraps around the ankle? Thank you


        Just over 9 inches.

        hope that helps,

        Size chart here:

          First off, I'll give the 5 stars because they are great quality and when you get a pair that fit, they fit brilliantly: nice and close to the boot and very easy to get on and off.

          I think the neoprene cuff could be tighter and I also don't see the need for the height of it, but these are minor issues and certainly take nothing away from the quality of the product; just suggestions on how I think it could be better.

          Now for the sizing. Do not use's size chart above. I have no idea what it even refers to but it's nothing to do with Gore footwear...they have never even made this in an XXL size and if they did it would only be a few guys with size 17+ feet.

          One reviewer below posted a Gore size chart that is slightly more accurate however these things are big. I have 3 sets of shoes and they are all EU44 / US10's: a pair of Shimano MTB shoes; a pair of Mavic Road shoes and a pair of Keen Springwaters for commuting. The Large size is marginally too large. It specifies 42-44EU/8.5-10.5US on the tag, but no way, no matter how fat your feet are are these going to fit a 42 or, in my opinion, a 43.

          So here's my size chart for these. Obviously buying online is tough as so many variables with diff shoes, but I think it's more accurate than anything published by either Gore or RC:

          S = 39-41EU / 5.5-7.5US
          M = 41.5-43.5EU / 8-10US
          L= 44-46EU / 10.5-12.5US
          XL= 46.5-48.5EU / 13 - 15US (I love the recommendations to buy this size below...pure gold)

          If you have wide feet, you may add a half size for variance I figure as I have very narrow feet.

          Good review: I wear a size 9 or 42 Euro and ordered a size large. The covers are way too big and fit like a size 10 or 44 Euro. I'm gonna need to return them for a size medium :(

          I agree with el pato and all you can eat. I wear a size 9/42 Shimano and a medium fit perfect.

          I wear a size 10 1/2 shoe. My feet &...

          I wear a size 10 1/2 shoe. My feet & fingers get cold frequently, way before my wife. Any recommendations for sizing and brand. The "Thermo" shoe covers appear to only come in size "36- 38", I'm not even sure what that means (Is it a European size?).

          Your best bet is probably an XL in any of the Thermo overshoes (Race Power Thermo is waterproof, while Oxygen Thermo is Water Resistant and wind proof).

          I wear a 10 1/2 shoe as well, and XL is the size I use.

          hope that helps,
          Robert, Gore Bike Wear


          Pricey but worth it

            The Gore Bike Thermo is pricey (normal price, but I ordered it when it was on sale) and what a product! Keeps the wind, water, snow, dirt, you name it, out of my shoes and my feet. These little things are amazing for a daily commuter or when training when weather conditions aren't very favorable. I highly recommend these!


            Be sure to verify sizing.

              RealCyclist sizing chart differs than Gore Bike Wear Sizing. Following the RealCyclist charts, my order came in too large. They handled the exchange quickly and effortlessly.

              Oh yeah, product is fantastic.

              Be sure to verify sizing.

              A bit big

                Its not winter yet, but just bought these. Take a closer look at the reviewer's pics, these open and close via a velcro strip all the way down the back, making it super easy to put on/take off. I wear Diadora size 42 shoes, the Large was WAY too big.


                Pricey but great performance.

                  These shoe covers are easy to put on and remove. I have heard of the horror stories about people leaving their shoe covers on their shoes because of the hassle that they want to avoid with putting them back on. Well these booties are the answer to your prayers. We're taking about 10 seconds to put on or remove them as opposed to the 3 round wrestling bouts you sign up for with the cheaper options.

                  As far as their performance goes:

                  1. They are water repellent.
                  2. Durable as they show little sign of wear from usage or washing.
                  3. Excellent in cold weather as they breathe well and insulate you nicely in below freezing temps. (I have worn them on 90 min rides in the mid twenties without even giving my feet a second thought.)

                  Yes, these are pricey but quality doesn't come cheap. Pony up the money and stop crying already. You spent 4 grand on a bike so what's another 100 bucks.



                    Overall, I'm really impressed with Gore Bike Wear cycling products, and these booties do not disappoint. Over the past 10-15 years, I've never found cold weather cycling enjoyable because no matter what I tried my feet got cold on longer rides (anything over 90 minutes). Not any more! These booties are really warm, and you can even wear thin socks underneath. So far, I've been on rides into the upper 30's with toasty toes (with the thermo lined model). The booties go on relatively easily, but it can be a snug fit if you have shoes with a wide toe box (e.g. northwaves), but maybe that's a good thing to help keep the elements at bay.

                    how do you determine the correct size? My husband is a size 10 wide

                    It appears he is an XL based on the Gore sizing chart.


                    Keep you feet warm and dry

                      These waterproof shoecovers are relatively easy to put on, with a velcro back closure and good fit for cycling shoes. Keeps your feet dry even in a downpour -- great for commuters. Not sure how durable the bottom material will be, but if you use these primarily on the bike and not walking, these should last long. Good workmanship, good quality, good product.
