Equipment and accessories will come and go, but your feet and back will be with you until you die. I think people often forget what a physical job photography is; you can be walking, standing, crouching, and kneeling for long periods of time. Not to mention hauling your gear around (don’t get me started about the trials of taking a large-format camera on the subway…) Definitely invest in good shoes, but you might also want to consider investing in a camera case on wheels.
You may not realize how heavy your gear is until you don’t have to carry it anymore. It will literally be a weight off your shoulders (and neck, and back). Most people can tough it our with one lens and one body, but as soon as you start adding more equipment, you might want to look into something more ergonomic. They are all designed for camera equipment, all have wheels, and most have room for a laptop, and are carry-on friendly.
