My Barrie shell LWBs fit snug. CXL Dovers are perfect in the same size (I think they stretched a bit). I take a half size up for my Van shell LHS. I may add tongue pads for superior fit, but I think I sized correctly for my feet. On a related note, I've found tongue pads work for loafers but not lace ups in regards to heel slip. Anyone else have the same observations?
