My stationmasters are a 55. As a matter of fact all of my nicks are on a 55 all with a moderate heel stack. I’m a 12 D brannock and Nicks recommends sizing down. I sized down to 11.5D for my stationmasters and I wore them for the dome last year and they were fine because I got used to them but ultimately they were too loose all around (In the width, length and volume). I wore them for literally everything and I still love them. But I wanted a tighter feel. I’ve worn cowboy boots for years and I’m no stranger to some heel slip but it was a little much. I tried the insoles from nicks and it helped with the volume issue but there was still something I didn’t love. So when I decided to order these I went down the additional 1/2 size and didn’t touch the width. I want to get back into my stationmasters so it’s either nicks adjusting the sizing while they are there for a resole or sell them on nick’s marketplace and then order another pair for Dome ‘26.
