If you don't wear them much they might last 20 years, but they aren't sturdy like cordovans. I only have 1 pair of Alden suede (snuff LHS) but they are the most comfortable shoe I own by far due to the flex sole. In the year I have had them they still look good and I haven't done anything special other than using waterproofing spray and shoe trees. But I also wore them 2-3 times a week all summer so they haven't been babied
Thank you for your responses gentlemen. Still under consideration.
