Take your actual body measurements as they are more accurate than measuring over your clothes or shoes.
Feet: Use a ruler or tape measure to measure your foot (from the heel to the tip of your longest toe) Be sure to measure both feet. Many people have feet of different sizes. Fit to the larger of the two.
Remember, feet can expand over a quarter size during a full day's walk so ensure you get the right fit.
Bought some new Merrels (Blaze 2 GTX)to replace old which had served well
However when trying them on it was obvious the laces were far too short
Go Outdoors provided longer ones which I thought were a free replacement, however not, was advised take it up with Merrel.

Had to buy longer laces
Very poor show Go Outdoors and Merrel
