There is no definitive answer to this question as everyone's feet are different and what may be comfortable for one person may not be for another. However, there are certain features that you should look for in a shoe if you want it to be comfortable for walking. Firstly, make sure the shoe has a good level of cushioning and support as this will help to absorb impact and reduce strain on your feet and legs. Secondly, choose a shoe with a wide toe box as this will allow your toes to move freely and prevent rubbing and blisters. Finally, opt for a breathable shoe made from natural materials such as leather or canvas which will allow your feet to stay cool and dry.
