A number of years ago I picked up some shell cordovan chukka boots at Ralph Lauren. Recently, the creasing pattern has become particularly substantial, as seen, with a high number of separate creases running throughout almost the entire length of the vamp. Most shoes, upon breaking in, will develop two or three folds near to the flex of the foot, but no more. For this kind of footwear, is the creasing shown at all typical?. What explains the number of location of creases in this case?
