Sounds like it to me. Does it hurt getting out of bed in the AM? (when your body is at its tightest)
I believe the footwear you choose directly impacts your chances of this. Going to boots in my opinion is going in the wrong direction.
Plantar Fasciitis issues are caused by the tightening and shortening of the tendon. I think this is caused by wearing shoes that have a raised heel.
I recommend not using products such as super feet, as they only contribute to the isolation and shortening of your foot tendons.
After your body warms up a bit in the morning try stretching your feet and calves. After this some careful and controlled toe raises, with the aim of slowly going lower as you loosen up. (over the that session as well as the following days)
I hiked for six months last year wearing Five Fingers, if you are not familiar with them the important thing to note is that they where neutral shoes, meaning they had no heal raise. My tendons where fully stretched out, from going up and down hills. A month after my hike ended I started to wear a pair of big clunky boots. After about a week and a half my "heel" on both feet started to hurt while getting out of bed or just general walking. Then it dawned on me why. The boots had shortened the tendons required range of motion. I immediately stopped wearing them and began stretching and doing controlled incrementally deeper toe raises, with in a week I was pain free. Listen to your body, don't push it, give it time.
If you do have a small tear in your Achilles tendon, RICE, DO NOT do the toes raises, try doing the ABC's with your toes, to promote circulation and get the repairing life fluids to the injured area.
I hope that helps!
