I bought the large for my Specialized women's Tahoe size 41 mountain bike style cycling shoes after reading reviews on how these fit small (size chart says I should be a medium- maybe if these were road style shoes). My shoes are bulky, designed for comfort if I need to walk around in them, and probably have more surface area than a slimmer design or a larger size road shoe. Rather than using shoe-foot fit as a guide, I'd suggest using shoe circumference as a better guide.

The circumference of my shoe is ~25 and 1/2 inches (~65 cm) all around from toe to heel. The large size shoe cover has to stretch a bit so I can close the heel completely. A larger size shoe in the same style as mine would probably have to get the XL. The top of the ankle is what I consider narrow and would benefit from more adjustability to accommodate different leg sizes and shapes without pinching. I've used these on some cold foggy mornings and they've kept my feet dry and warm. I have yet to try them in heavy rain or snow.

These booties are super nice quality and I love the screaming yellow, but people are not kidding when they say to order up. I wear a women's size 7.5 street shoe and my MTB shoes are Shimano size 38. The shoes are a trim style for MTB shoes, not boxy and with no rubber toe bumpers or fat soles. The sizing chart says to order small; I ordered large because of the warnings in the reviews. The large booties took lots of tugging to pull on, and the velcro barely touched at the heel. I exchanged them for XL (thank you Amazon for your excellent return system).

The XL booties fit over my shoes and come together at the heels and ankle, but apparently they are designed for someone with skinny legs because they don't come together at the top. I do not have especially large calves for someone who exercises regularly. Unfortunately the fabric is not stretchy so there is no room for adjustment. The XL booties are still good enough as my rain pants cover my calves, but buyers beware! I suspect that Pearl Izumi simply changed the bottom of their road shoe booties to accommodate MTB cleats and didn't bother to adjust the design or sizing. Lazy work in my opinion. Women with small to medium feet and skinny legs, you have found one heck of a bargain.

These are awesome for keeping the feet dry. They would be 5-star shoe covers if the sizing bore any rational relationship to even Pearl Izumi's shoe sizing, but it does not. These run small -- quite small. I sized up two sizes, and these are still hard to get on. I'd have sized up more, but the XXL is as big as it gets. (They fit - tightly - on a pair of Pearl Izumi size 12 mountain bike cycling shoes.) The fabric is not one with any "give" or stretch, so do plan to go larger!

Once you find ones that fit, they are really nice covers - almost like having cycling boots. It's nice to keep your feet dry; life is so much warmer that way. There are more and more mountain bike shoe covers coming onto the markets, and I am guessing that one can find similar covers for lower cost than the Pearl Izumi brand name ones. That said, my husband is a big fan of PI products, and they have proven durable over time, so that's what he prefers.

These run extremely small! They're listed as being mountain bike shoe covers, so you'd assume they would be on the larger size (since MTB shoes are generally larger than road shoes). However, the XL doesn't even fit on a 42-43 (US size 9.5) Specialized 2FO. That would generally be considered a Medium shoe size... Returned them to try the XXL, but I may have to return those too.

Well bummer. Got em out for a hard rainy 1 hr ride but my feet still got quite wet. Strangely, the water wasn't coming in from the cuff/top but through the upper toe area and top of foot. I speculate that the seam on the top and the seam along the sides are leaky. I'm disappointed. For that degree of protection I could have gotten cheapo neoprene covers. I expected more for the price. Also, what is up with the sizing? Do they even have real sizes or do they just slap whatever tag they want on a one size fits all? I wear 41 (7.5US) shoes and have calves of a normal uphill rider but could barely get size XL shoe covers on. I should be able to run a medium based on their fit charts. don't bother with these, get something cheaper.

I liked the stretch of the material and they seemed like they would add some good warmth. But the issue is the sizing. My mountain bike shoes are size 11 (euro 45 maybe) and so I got the XL as recommended. Too small. Returned and got the XXL. Still too small and not by a tiny bit either.

What kind of shoes do they think people Mountain bike in? Little carbon shells? My shoes are just shoes with SPD that I can walk in (they have tread). That doesn’t sound crazy to me.

I wear Sidi size 43 MTB shoes and had no problem fitting these size Lg over my shoes. There is some stretch to the material but it doesn't compress/squeeze my toes. Mt Sidi shoes are ventilated well for hot weather riding, so that can mean cold feet for me as temps creep below 55 for my 2 hour commute. These block the wind nicely and even with thin socks I was comfy. I have not yet been caught in the rain but a little water hose test went well. I have some Pearl gloves made from the same material and they are thin, warm, and very water proof.

Best pair of covers ive owned. I love how bright they are, how easy to put on they are, and how reliable they are for up to 20 degree weather and beyond

Pedí XXL en base a los reviews y que bueno que lo hice. Los tenis son Diamondback del nro EU 43 y muy apenas les quedaron (según la guía de tallas de Pearl iZUMi, L debería haber quedado), tengo que darles un buen estirón para que puedan cerrar la parte trasera de los tenis.

Si tienen tenis más grandes, no creo que les queden.
