This is kind of a continuation from my log. But, can tights interfere with your normal stride? The reason I ask is because I ran a 5k last night. It was quite cold, below 30 degrees F. I wore long tights for the 1st time ever running. It felt difficult for me to raise my knee to its normal height after I would push off the ground with that foot. It could have been the temperature or something else but the tights almost felt restrictive.
