The beauty of microspikes is that their easy-to-use harness systems make them compatible with many different types of footwear. Generally, most will use their winter hiking boots or trail runners, though with the proper size, microspikes can even fit on ski boots for a non-slip walk across the ski area parking lot.
Be mindful of the different styles of footwear you plan on using your microspikes for, as their size range may not accommodate all of the different boots and shoes you’d like to use them on.
