When vegan you probably did a pretty good job of avoiding leather, silk, etc., etc. The one thing that I never found a truly good vegan substitute for were dress shoes. I tried a lot of different companies and products.
The first time I went to the store and tried on my now favorite pair of shoes ever, I experienced something that I didn’t know could exist: comfort in wearing a dress shoe. You just can’t beat the quality of a well-made pair of shoes. The pair I slipped on happened to be made by Florsheim. We’re talking about no cutting into the ankles, no I-think-I’m-wearing-shaped-plastic feeling.
