In reply to matejn:
Maybe just unlucky, but the very front of the sole on one of my boots "ripped" on a sharp bit of quartz!!
No problems so far with the zips (2 seasons in them), though can be a bit of a faff to use with big gloves on if you need to do any adjusting. But then again, so is tying your laces on normal boots!
Light, warm, comfortable, love them (got them at a very good price as well, over the moon as there's no way I could ever justify shop price, for these or any other boots!!).
If you don't buy them, and they're size 43, please let me know....!!!
Cheers,
Gordon
