So I wear my shoes for 8 hours a day and then take them off when I come home. Some people where their shoes all day. If I only wear my shoes 8 hours a day and let them rest 16 hours a day, the ratio of wear to rest is the same as that for someone who wears their shoes all day and let's rest for a night and a day. 16/48=8/24 So I'm asking is the rest theory because of the assumption of 16 hours of wear? If 16/48 schedule is better than the 8/24 schedule, is a schedule of 16/72 better still?
