I've been putting some miles on my Asics shoes, and they don't feel quite as comfortable anymore. How often should I typically replace them?

Most of the time, you should replace your Asics running shoes every 300 to 500 miles (480 to 800 km), but this can change depending on several factors.
There may be a need for a new pair of shoes if the ones you have become less comfy after a lot of use. Total miles, frequency of use, terrain, body weight, and running style are all things that affect how long shoes last.

A heavy runner or using them a lot, especially on rough surfaces like concrete, can speed up wear and tear. Overpronators may notice uneven wear patterns, which means they need to be replaced more often. Also, even if you haven't hit the suggested mileage range, less comfortable shoes could mean that the cushioning and support have worn down, which means you need new ones.

However, there is no exact formula for figuring out when to get a new pair of Asics shoes. Paying attention to signs of decreased comfort and taking into account things like mileage, usage patterns, and running terrain can help you make an informed choice.
