In reply to kestrelspl:
Hi I had loads of problems getting my feet used to my old style Nepals when they were new, from heel stripping blisters to severe foot cramps, when I took the boot off. A lot of it was sorting the lacing to just the right level, I have a high instep, which doesn't seem to help.
All settled down now and I am happy with the boot, though heavy for long walk ins.
I have had them resoled with a new sole unit, don't think I could start again with a new pair!
Some good advice given already, give consideration to good quality socks, including a liner pair and and a good sole insert the standard one is pretty poor.
Good luck,
Jon
