Bought these to fit to a pair of boots I have but they are too small.
My boots are a US 13 and slightly larger than standard 12 as I had them resoled with a larger rand round the outside
The gaiters are just too tight and deform the boot a little due to them being softer leather and a flex sole (non Vibram)
These would be perfect for a 10-11, a 12 at a push if they have a rigid sole like a 4 season walking boot
The centre sole strap has been removed to allow them to fit non- Scarpa boots (Personally i use some silicone on the rand around the toe and midsole anyway)
These have the newer improved rand, have been fitted and removed
