Many different options exist to help keep your feet warm when running outdoors in the cold. It can be difficult, as sometimes it may not be an extremely cold day, but there is the possibility of ice to slip on, while other times you may have to use warm shoes or socks, or even toe warmers in the cold. One example is that of the HeatMax Toasti Toes Foot Warmer (40 Pairs) seen below, that you can use out on those cold runs to help keep your toes well-circulated and warm during the workout.
So, it is more important to consider the overall weather that exists in your region if you plan on continuing to run outside throughout the winter season. If it is only very cold for a short period of time, there is no reason to spend a lot of money on expensive shoes when you will add warmth to your feet from inside. Another option is the Meister 2.5mm Thermal Neoprene Toe Warmer Booties for Running (Pair) that can keep your toes completely warm while the rest of you is fighting the cold air of the winter weather on your workout.
Now, you may have plenty of options to consider, if you are willing to purchase another pair of shoes for those chilling winter days. However, with plenty of options available to keep your feet warm from inside the shoes you already own, you have many choices to help save money on purchases that may not be needed. One of the best things you may consider is how often you actually run outside in the winter, or even if there is a long winter season where you live (or a great deal of cold weather in the winter). If the answer is no to either of these, it may not be worth spending over a hundred dollars on a pair of warming running shoes so that you can keep your feet warm and functional with just a little support in the shoes you already own.
