The choice of outdoor clothing we use is just as important as our choice of camera equipment. If I am comfortable, dry and warm while out on location, then this goes a very long way to allowing me to become absorbed by the process of making images.
For many years I have used Scarpa hill walking boots for my outdoor photography pursuits because they give me great ankle support in uneven terrain. They are also made of leather and with the right waxing, are completely waterproof. They are of course a personal choice and just about any outdoor hill walking boot with sturdy ankle support, that is waterproof and has a firm sole (which will not twist and bend when walking over uneven terrain) will suffice for most of what I do.
A year ago, things changed for me. I took a chance and bought a pair of Muckboot 'Arctic Sport' boots. I have been using them in places where there is lots of snow or water. They are like a wellington boot on steroids with thermal insulation, a rigid sole and they are absolutely waterproof to just below my knees. I have found them to be extremely comfortable, warm and dry and I can even wade into water that is more than a foot deep.
When I bought the Muck Boots, I wasn't sure if they would have sufficient ankle support go give me stability while walking over uneven terrain, or navigating down rocky slopes. I have found them to be sufficient at this, although I do believe that nothing compares to the ankle support that I get from a traditional pair of hill walking leather boots.
The Muck Boot Arctic sport boot has become my favoured boot of choice for most of my photography, and I am now finding that I feel less of a need to take a traditional pair of hill walking boots with me, because I often flood them since they are only waterproof up to my ankle. I think having a boot that allows me to get access to shallow streams and to cross areas where the water is more than a foot deep is very useful.
So I would really definitely think about these boots for winter photography. I am not sure they would be suitable for summer or warmer climes as they are well insulated, so your feet may boil.
One last thing, I have also found that a pair of microspikes has become invaluable for my photography also. It would be easy to assume that micro-spikes are only required for icy conditions but I have found them very useful for slippery rocks and some beach areas where the rocks are slimy. Just this week while on the Lofoten Islands, we had no snow, but everyone was commenting on how secure they felt while using them in areas where the rocks were slippery.
So in a nutshell: if you do a lot of winter and beach photography, the Muck Boot Arctic sport is a very highly recommended boot by me, and I would also suggest you buy a pair of Kahtoola micro spikes and keep them packed *always* in a side pocket of your camera bag.
