I would say what Matt is referring to is the heel to ball bannock, which is the most important. I have many pairs of GS in both Leo and Floyd lasts as well as a few Alden’s in the Barrie. To me, the Barrie is similar to the Leo, but just a little more snug overall; it’s a wonderful last. I have a similar preference as you (snug heel, roomy toes) and your best bet might be the 7.5E, but your heel to ball will be the biggest determine factor, I’d imagine.Ordering from overseas. I have to be as precise as possible. I will order 2 sizes once I tried the Barrie last here in EU as it’s supposed to be very similar to the Leo last from Grant Stone
