Feet are a size larger by late afternoon, and larger again on a hill
When to try them
Late afternoon, in walking socks. Feet swell through the day and considerably more on a long descent.
The heel test
Kick the toe against the floor, lace firmly, and walk down a slope. If the heel lifts more than a few millimetres, they are wrong whatever the length.
The toe test
You should be able to just touch the front with your toe when the boot is unlaced and pushed forward. A full thumb's width is the usual guidance.
