The shaft is really, really wide

Ever since I started taking one of my meds my legs started to swell and there is no alternative med to fix the issue.  I can't zip up the boots I used to wear.  Their opening diameters at the top of the shafts are 13.5" to 14".  These boots however, have opening measures approximately  18.25" around.

If you have larger calfs and gave up on the boots, these are the best boot you can buy.  As for me, they were way too wide and returned.  I found the Midum shaft size of 15" (Topic 41347 Boot) in the same design few days later.  They are perfect fit for me and loving them!
