I understand the sore feet. I too work on my feet. If your doc approves do a mile or two an hour or two after work; before going keep your feet up. Comfy walking shoes bought AFTER work will help! From a guy who walked 2 miles and built it up to 6 over two years (walked six miles/day for the last year) before switching back to the bike cause I can ride in the 100 degree heat and have a BREEZE!!

You will not get out of shape as much as you will lose your conditioning; by that I mean you will still be in shape but you will have dropped back in desire and your body will protest not like it did at first but it will still ask you what the heck you think you are doing!?!?!? I took off about 4 week becasue of my son's ballgames, not feeling well (had the bug that is going around the area) and then the heat. The one at my house who got out of shape was my walking partner; Bear the wonder dog! HE thought that we should go daily.
