Boots change the relationship between a trouser hem and the ground. Sandro's men's boots collection is a place to consider that footwear direction, with jeans offering a familiar base for judging the proportions. Decide how much of the boot you want visible, then keep the upper outfit consistent with the result.
Availability may vary in this selection. The main men's footwear collection provides alternatives when no boot styles are listed. Check the individual dimensions, size information and description where available, rather than assuming that a named category tells you how each pair will work with your wardrobe.
