We didn't have time to remove footwear at rest stops although ultimately had to just to drain blisters. Only water pick up points every 2 hours and then a break for lunch. Stop and change socks when you can
Feet were swollen by day two and releasing laces was a essential to release cramped feet.
Numerous 16 mile walks in preparation didn't set us up for the 30 mile middle day.
One of the things I would definitely do differently is take more than one type of footwear. My Brasher walking trainers were great till the weather turned bad. Then I wanted my Boots. They would also give hotspots and sore bits a chance to heal by having potentially different touch points. In the evening a pair of Crocs or flip flops would have been amazing.
Hope the following doesn't offend. 2 are my buddy Pete and one is me.
