I would get on ebay or check out garage sales and look for C.A. lund wooden snow shoes that are 10X56. They where made in the 40ies and I think the 50ies for the Military. They are the best pair that I have ever found. They have a big upturn on the toe 10" or so. What that does for you is that that you don't have to raise your knees as high and it will save enegry. If you can find them they run about 200 or so used. If you look hard enough you can still find them brand new. My second choice would be snocraft. They where made on lund jigs. They where made in the 50ies. Wooden one will give you more loft, will not collect as much snow on top of them, are more quiet then alumium ones. You can get leather bindings and they will fit different size boots. So in the early winter when you are out in lighter boots the bindings will still fit and then in the middle of winter when you have pack boots on you can just mkae them bigger to fit the bigger boots. The only maintance that I have done is every year is put a coat of marine varnish and then inspect the bindings.
