Shoe care and recommendations?

I have had a particular pair of shoes for about four years. They are black leather slip on shoes that vaguely resemble "boots". They are nice enough to wear to the office and rugged enough to wear for long periods of time. However, after four years of wearing them for 8-16 hours a day, 5-7 days a week (and at one job for almost 3 years I was predominantly standing in them), they are not doing so well. They are wrinkled and stretched out, the cloth and foam supporting the heel has worn away, and I have to replace the insoles every 3-4 months.





So here are my questions:





How long is too long to keep a pair of shoes? I am starting to wonder, if insoles cost about $10, so $30-40 a year and the shoes cost $80, I am starting to waste my money.





Next: What are some tips on taking care of leather shoes, and shoes in general, to make them last longer.





Last: What is a good brand of work shoe? They have to be available in wide width, be comfortable, and have good ankle and arch support!





Thanks!

After four years of constant wear, I don't think you should be asking for advise on how to make shoes last. I've had a pair of New Balance runners since 2000, but they're only worn when I run. As long as you still like the shoes, I say keep them, however, once they start looking aged, I'd stop wearing them to the office.





The main key to keeping leather shoes in good shape is to keep them dry. If they are polished, some kiwi from time to time will make them last. If not, try leather conditioner.





You didn't mention the kind of work you do.
