Question: what is the difference between nike metcon 3 and 4?
Answer: I'll get into more detail on the differences between the shoe later on in the article, but the glaring difference between the Nike Metcon 3 and Nike Metcon 4 is the upper material. The Metcon 3's utilize a heavier duty mesh upper while the Metcon 4's have a much thinner, lighter, and more breathable fabric.
