Well, it's just a hunch, but it seems logical. I also have a pair of natty cxl plain toe Alden boots that I'm worried about stretching because the Trubalance last is already pretty voluminous for my feet! Anyone out there with CXL White's want to relate their experience with stretching? And, on a side note, do the smoke jumpers etc. use a thicker piece of leather than the semi-dress?
