Thanks for your replies so far
. I wanted to answer a couple questions that Carla pointed out, as she made good points, but sadly I've made sure to cover all those bases and am still stumped!!!
First, I have had the running room re-lace my shoes in a pattern designed to take off pressure. I also made sure to buy the running room's special 2 layer/ no blister system thin running socks. Also They fitted me for my shoes, so there is ample room and they really do feel nice. I think what the second poster pointed out (I'm sorry I've forgotten your user name!), Could be part of the problem. I may be trying to jump into too much too fast. I have gone from completely sedentary to 5km walks and interval walk/jogs in 1 week. allthough, I am careful to wear a heart rate monitor and stay between 152-165 beats per minute (about 70% my age predicted max) My bones and feet may not be able to handle the new pounding I am throwing at them!! I sometimes try to slow down to a walk and I feel like I am not going fast enough to make a difference... remember I have BIG goals this year with wanting to join the military!!! And I HAVE to be able to run in basic training with no feet problems that could possibly have me put back and re-coursed! Back to the walking.... when I slow to a walk I feel like I must be going too slow (it feels under 4mph).... My heart rate drops to my lower end ( about 145 BPM). and I feel like I am not pushing myself hard enough. I know I am capable aerobically of the walk/jog intervals.... my feet just keep stalling my progress!! My feet are sore along the bottom this morning ( forcing me to walk timidly/ not quite a limp) so I may have to take today off completely and do what was mentioned (switch to the stationary bike) for my next cardio workout on Monday. I truly hope this works itself out because now that I've decided to move, I do not want ANY excuse to pop in my head and make me procrastinate any longer! Any more thoughts out there? Thanks for all your help!
