Crocs don't wear out as fast as some other shoes but they get so dirty, I'm ashamed to wear them. I got an almost new condition pair at a thrift store for only $3 but they look really bad. I tried different household cleaners and they still look bad with black scuff marks and an overall impression of dustiness.For those that like shoes I would suggest trying a pair of Ecco brand Moccasins. Probably the most comfortable pair of shoes I have ever found. They are also very durable and will actually be cheaper than buying multiple pairs of tennis shoes.
A couple of years ago I switched to Whites boots. They are all hand made in Spokane Washington. They are all black and very heavy. They are all leather and mold to your foot as you break them in. The support for your feet and back is tremendous. I am going on two years with the pair I have now. When they wear out you can send them back to the manufacturer for a rebuild. Essentially you get a new boot for half the price. They will also custom fit for your feet. They have no cushioning insoles in them but are still the most comfortable foot wear I have used once they are broke in. https://cleanerprofy.com/how-to-clean-white-crocs/
Is there a secret Crocs shoe cleaner that everybody knows about except me?
