That’s why I primarily pack my toe warmers when I’m riding in the winter months. They are the perfect compromise and made from the same water resistant neoprene that full booties are made. They are easier to get over your cleat and on your foot too.
One ride in these and you’ll realize that covering the mesh vents on the front of your cycling shoes are usually all you need. By blocking the wind chill from your toes you can stay cozy and ride longer in chilly and freezing temperatures.
If you plan on riding in wet, rainy or snowy conditions then get yourself some full shoe covers, but buy those as an after thought. Chances are you’ll use the full boots less, I recommend getting a pair of toe covers first.
They will probably come in different sizes too, a small/medium for smaller feet and a large/x-large for sizes over 42. My feet are a 46 but the L/XL always fit fine.
You can usually walk around in them too but when they get caked with snow and road grime they’re less fun to take off. Still that’s being nit-picky and a small price to pay for a better attitude at the end of a chilly ride. Besides the full booties would only get dirtier anyway.
Unless you ride in a climate where the roads constantly remain wet in the winter months you’ll find toe booties go on quicker, easier and still do the trick.
