I can second LSR from experience when I needed a pair of nearly new boots resoled as they had cracked up while stored.
LSR did what they say on the webpage - provided recommended options and a timescale, which they delivered to at a price cheaper than new boots.
I'd also recommend LSR. I understand a lot of the staff are ex Karrimor who had a really good repair department in their Accrington factory (before Sports Direct got a hold of the brand and moved all manufacture to the far east). Anyway, this lot have been fixing stuff for years and are based in sunny Burnley now.
Tisos in Edinburgh have an in house cobbler who can resolve and repair boots. I have 15 year old pair of Scarpa Mantas that are on their 2nd sole. He has also repaired the internal lining. They are winter boots with full rand etc.
