You will need proper hiking boots - trail shoes are not good enough. We'll be taking you to some awesome places where you'll be hiking over a variety of terrain, therefore your boots should have full ankle support and a stiff sole with a high profile tread. It's also important that whichever footwear you decide to bring that it's well broken-in and waterproofed before you come down. If you have good ankles that will be able to cope pretty well with varied terrain, then good hiking shoes should be fine, but if not then hiking boots will give you better support.
