Take care of your shoes
When buying shoes, it’s important to focus on quality, not price. Shoes made from full-grain leather uppers, rather than corrected grain, will look better with time, and if the soles have been stitched on rather than glued, they can withstand up to twenty years of semi-regular use (with occasional resolings, of course). Compare this to most shoes on the market, which have to be discarded after two or three years, and you can see which provides more value.
This is only true, however, if you take care of shoes, and to do so, you’ll need the right tools.
