Clothing is something we've been using for who knows how long now, even some of the earliest civilizations have employed clothing in their lives. The use of clothing has been due to a few factors, the most important of which is heat that clothes help insulate us from the cold, and footwear specifically has had the important task of protecting our feet from the cold and hard ground, putting a barrier between the skin and the ground. And with time the footwear was made into different methods and styles for different terrains and climates. Shoes are usually used in warmer climates whereas boots are used for long trecks and colder climates. And simplicity is the primary key to making footwear more comfortable, namely the more materials and the less fragile and tearible parts the more durable the shoe.
There is a fair variety of shoe types in the world the most common of which is the sneaker due to its simple design and build. Depending on the path you take on the daily you might want to get a certain type of shoe that fits the terrain you'll be walking on. If you're walking on pavement often then sneakers would be the most comfortable since they have a rubber sole which is significantly softer and more comfortable than a leather sole which is much stiffer and would be very uncomfortable if not sized correctly for your feet. However, you do not need to get designer high-class shoes to get a quality fit, you only need to look for the right shoes if you're going to buy mens casual shoes. Again you'll want to consider what you're walking on as a first priority. If you're going to be walking through a heavily forested area often you'll want dedicated hiking shoes since any normal sneakers or any other casual shoe will be destroyed on the path.
You're going to need to choose your shoes to match the clothes you wear most often, you don't want to wear formal dress shoes with a pair of jeans and a t-shirt. That's why you should look at your personal style and buy mens casual shoes accordingly. You should look into the various styles you're interested in and decide by either taking up one established look or go with a combination of a few different styles to create something truly unique. However, shoes will always be shoes so going wild with them should only been done aesthetically and never with the materials, to avoid discomfort.
