Should shoes only last a year????

Good morning,I would like to firstly acknowledge the perfect style that Markham has always provided me with and always being in line with the latest trends but today I write this message with a sore heart only because of the loafers I bought from your store last year July I wore them at a prize giving event I was invited to and the best time was when I wore them at my wedding and also noting I always wear them with secret socks but today I wake up to an open sole in front as well as the back as if they were bought at some Chinese store (for temporary use) as a bread winner at home I started buying clothes at Markham for my younger siblings but I have decided i will honestly stop also not allowing friends to go through this amberrasment....I kindly request you rectify this and please let me know what can be done to fix this they were bought at Markham Rustenburg mall in July last year.
