neoprenes wouldn't work. it can be cut and torn unless you get a thicker suit which would actually be time consuming to put on and would hinder movement.
A shark suit would be heavy but would do the job at preventing injuries that are not blunt force
something along the lines of the neptunic . I personally would not wear a shark suit as they are heavy and will slow you down. Also I would not want to be wearing one in hot temps with a heavy sun.
Your best bet for clothing is to wear thick close fitting clothing. Boots or running or hiking shoes preferably water proof/ steel toe. Some wool socks would be wise to fight off cold toes and help insulate your feet in water or cold temps. A hat for cold days(remember ~80% of your body heat is lost through your noggin) or to keep the sun from over heating your brain. I would also invest in some gloves as you need your hands to be functioning so having them cramp up due to cold is a bad idea. A back pack to carry essentials such as water and food, maps, compass, flashlight, lighter and matches, mess kit if you want one, medical supplies for non zombie injuries, communication devices, pens and pencils, and a blanket or towel and a multi-tool. You should now be able to survive longer.
