In reply to Bjartur i Sumarhus:
The Aigles are excellent wellies for walking in. Like a number of the more expensive wellies, they have proper footbeds designed for walking in. (they also do lace up wellies - or did so a few years ago)
In comparison to similar priced leather/material 'walking boots' they'll outperform them in terms of comfort, durability and certainly waterproofness. And you'll never ever have to bother clean them or reproof them either.
I do recall a conversation I had with a chiropodist who said he dealt with a number of foot problems from regular wearers of cheap wellies which don't support the sole/heel or ankle in the same way boots or more expensive wellingtons do.
