Not sure if hiking is considered a sport but it is one of my favorite past times. For years I have enjoyed my Saturday afternoon (outside of football season) romps in the woods and even occasionally do some Appalachian Trail hiking. Being retired now I am planning on spending some time on the AT this summer and have been doing some local hikes to get ready. Now to my question. About 10 years ago I was diagnosed with type2 diabetes. The past year or so like many diabetics I feel some numbness in my feet and they are much more tender than in the past. My hiking shoe of choice has always been Merrill moabs, super comfortable and an awesome shoe however lately the moabs tend to cause cramping and soreness in my feet after 3 or 4 miles on the trail. Moabs have a very hard sole and are not as flexible as some other shoes. Monday I decided to switch shoes so I bought a pair of New Balance trail runners. Yesterday I took them for a 3 or 4 mile test hike. Much better results but still some cramping late in the hike. If I can't do 8 to 10 miles in a day there is no sense in me going back up to the AT. Has anybody else experienced similar problems and do you have any suggestions? I'm thinking frequent breaks but I hate to be sitting on my ass when there are miles to be made.
