Worst shoe manufacturers

Good day shocked with service I received from caterpillar I got a pair of shoes that disintegrating after 6 months of having the this happened over December so I thought I will send them in in the new year thinking they have a 12 month warranty but I was wrong. My fight is in the box there is a stamp with a date 2021 is this a manufacturer date or expire date, Making my shoes 3 year old already this is a big consern. You are buy the shoes already old. So I am sorry caterpillar this is shocking and I will not be supporting you again and my friend and family.
