Yorkshire Boots [Alt-Bergs] bought at in Warm & Dry, Whalley [Lancs] - - a very good recommendation!
I walk an average of 40 miles per week and having the right fit is really important.

If you have average feet you may get better value with a different make, but still a good fit is crucial

My experience of re-soles is poor so I get my boots re-heeled as required at a local cobbler until the soles are too smooth to use

Boots are expensive but even so walking is a cheap hobby

I've been enormously happy with my Yorkshire Boots [Alt-Bergs] bought at in Warm & Dry, Whalley [Lancs] - a family owned business which offers a unique expert fitting service. Alt-Berg make boots of various width sizes.
Anyway - my problem wasn't shoe wear not lasting - it was more getting blisters - so you might not want to splash out the cash on these.

I have similar problems buying expensive boots that last 12months at the most - is £130-£150 a sound investment for a year. Some would argue that it is I'm sure, however I'm still to be convinced. My most resent purchase was a pair of £30 Hi Tec mid-boots from Go Outdoors, they appear to be holding out well so far.

I need to buy some new walking shoes and I wondered if anyone has anything to recommend. I need some with a thick sole with plenty of grip and that don't wear out after 6 months. The ones I've had recently have worn out in no time and they weren't cheap!
