Hi, I have a pair of used Edward Green (for Louis Boston) slip-ons for sale. They are size 8 1/2, US I expect seeing as they are for Louis Boston. Assuming I'm measuring them correctly, the soles are 11 3/4" x 4". They use the 184 last and include trees (although it looks to me like the trees are for the 202 last - see picture). You'll notice one of the trees is missing the pull-ring, but it's still quite easy to get in and out. I think this is a pretty good deal for the shoes including the trees. Sorry if the pictures aren't the greatest .... I don't have a proper camera easily at my disposal ... just added some pictures of the sole measurements. I'll cover shipping in the 48.
