Gorman shoes - run large or small?

I have a store credit for the one item i've ever purchase from Gorman...been struggling to find something else I might like but some boots have caught my eye. For reference, I vary between a 37 and a 38. In Bared i'm often a 37, in Jo Mercer I seem a solid 38, and in EOS I can be either 37 or 38 depending on the shoe.
So i'm wondering, does anyone have experience with Gorman shoes and know whether they run a bit tight/small? Being rural I don't have capacity to try on, so my dilemma is i'll be getting these shipped and don't want to faff about too much with a return/exchange again. Thank you so much for any advice
