Socks make a huge difference when it comes to running.  Ensure you’re using socks that are made of technical material, cotton is rotten and will aid in helping your feet blister…I will bring various sample socks so you can refer to. Some runners like thick socks, some like thin socks.  The choice is what makes you feel and run smooth?  You’ll want something with a type of arch support from your running.
Compression socks are another choice. Some folks like them, they make a difference but they are a bear to get on and remove.  We’ll discuss socks on Saturday as well to help you see and feel the difference in socks.  I like the bamboo combination, along with the L and R on the foot bed.
