Review via - 11th Sep, 2019Always gone for Merrells - they fit like slippers straight out of the box with no breaking in required EXCEPT - this time, after wearing them for a days travelling with only a small amount of footwork required, I got a blister on my right heel where they had started to rub. Investigation revealed a very slightly raised seam at that point. Compeed applied and no further problems, but I hope this isn't indicative of falling standards. I have not yet tried the second pair purchased at the same time, but will be more cautious with them. So, four stars instead of five. If the other pair rub as well, I reckon we're down to three - time will tell.
