I wear Barrie/Trubalance 10.5e or 11d. My Rancourt shell beefrolls are 11e and I'd say they have a little too much volume (solved with a tongue pad). I have a pair of lined suede rancourt mocs on now that are 11d and a tad in the tight side (particularly with socks). Considerin all that, If I were to order a new pair of shell beefrolls today, I'd go with 11d. It would work well for me sockless and with lighter socks. Hope that helps.
