I travel almost every 3-4 days/week for work. I carry on my luggage but between dress shoes and runnnig shoes for my workout, the shoes always tend to take up the most space in my bags. I am wondering - is it damaging to my high quality shoes to take only one pair a week but wear them on 3-4 consecutive days and then give them 1-2 weeks off completely and then repeat the cycle. In aggregate, say over a 3-4 week period, i would be essentially wearing them the same amount as every 3rd day....but i suspect that it is the consecutive days part that would be harmful? I would be able to put them in shoe trees overnight, while on the the trip - if that would make a difference? thanks!
