I wear the 2620s when I play for my local team to keep my feet strong and flexible and eliminate foot pain and toe numbness.
Any footballer I know has foot issues. From severe plantar fasciitis (usually heel pain) to just generally sore and beat up feet. The 2620 orthotic insoles alleviate these issues as well as preventing future issues buy passively exercising the feet.
Boots are damaging to the feet because they do not let the foot to do its job which is to flex and splay and expel all that force you are exerting on it.
My aim is to get your foot to move inside the boot in the most biomechanically correct and efficient way possible.
