In reply to Tigger:
Unless you love the shoes don't bother. Every pair of resoles I've ever had I've ended up not using:
Cheshire - shoes radically changed with large "beak"
Feet first - shoes radically changed
Llanberis - great job but delaminated (pinks) - possibly the only shoes I'd have kept otherwise
George in Greece - great job but 1/2 size wider (pinks again) although others did better
They are all expensive but it's a skilled and labour intensive (and unpleasant) job
