When I woke up this morning I felt much better.  
I went to the outskirts of town to buy walking shoes on sale. Around 70 € off normal prize so I was happy I found the shoes. They're Asics and since I have a pair of jogging shoes in that brand I thought they would be an option now that my 13 or so year old Nike shoes have done their duty... I've been walking in them for so long and I didn't even think that they could be the reson that my feet's been in pain for a while. Especially the heels are so bad that I have trouble walking in the morning. I started to suspect that my Nike was the reason and looked at the sole and there's hardly anything left! No wonder my feet hurts after the morning walks and then being on my feet through my work day (although I change shoes at work) and home again. At first I thought I'd use my old, comfy, sturdy hiking boots, but after talking to mum I realised that she was right... I'll get really warm in those boots...  
The Asics are also a Gore-Tex shoe (as my old Nike) and have some special gel sole in the heel part. Since my size was sold out I tried halv size down and one size up. Both were ok, but the size up was slightly better. Really comfy shoes! 
When I walked to my first bus, I felt how tired I still am. So drained from energy. I hope next week will fix that, since I'm off to work tomorrow. I need to go, then I can rest again.
