Until I can afford better walking shoes I'm not taking walks!  

well the best walking shoes i have came from a charity shop and cost £4 - you could try secondhand shops or even freecycle. or ask around your friends perhaps for a pair you could just borrow now and again.

Hi bluespacker, I walk a bit in the winter and don't use special walking shoes but then again it's not over rough terrain. If you're just walking where the conditions aren't too bad in work breaks then just try what we used to call 'pumps' in the UK, they were basic gym shoes before fancy trainers were invented. Mine are just in light water proof courdroy with lace ups and a reasonably good sole and were cheap in a sale. I only walk less than 2 miles at a time though but they've proved fine.
Walking is an excellent way to keep the weight off and to tone up, just remember always walk straight with stomach in and chest out and with neck aligned, and never forget the bottle of water.

We should not find excuses to avoid walking.If you want to lose some weight seriously,you can always find a way.You can ask an advice from your doctor to avoid those blisters.In fact,walking with bare foot is good for your health.Since there are more nerve endings in the foot,they will be well stimulated and improves your health factor.
By the way,this post seems 3 months old,what is the improvement you have seen in these days?How much weight you have shed?

I saw this one at the top of recent posts, but I see its a 3 month opld post.
I wondered how you had got on in your search for better walking shoes.
I think I saw thrift stores mentioned further up the page and I think you would be bound to find a pair in such a shop.
I see from your comment to the previous poster that you havent shed any weight in the last 3 months since you posted this.
Have you considered swimming or some other form of excersise

I do know that they have some kind of material that a person could put in their shoes to keep from their blisters and bunions appearing. I think that it is the Healthy Living magazine by Amerimark. I once walked with sandals on when I was pregnant with my third child, and I had a dark mark from my shoes. It was formed around the straps of my sandals on my feet. The straps rubbed up against my feet as I was walking and it caused a mark. I will never walk like this again with sandals on.
