Packing for walking
Pack waterproof overtrousers if you intend to walk and explore; nothing is worse than soaking wet trousers except.......soaking wet feet! So you *do* need sensible walking boots/shoes (the ground can be rough) which won't let in the water. Take more pairs of socks than you usually do, just in case your boots leak. Don't underestimate the risks. Whilst Shetland high ground is not especially high, its weather conditions can be as challenging at the Cairngorms, with rabbitholes, rocks and boggy ground ready to break your ankles. If you plan to walk in the wilder parts (such as Northmavine) make sure you have the right emergency gear (food, whistle, spaceblanket, first aid kit, phone..although it may not work) and know how to use a map and compass. I've experienced mist in this area firsthand; without map and compass you will be really stuck. And do make absolutely sure you tell someone...
