Black/eggplant Mamimo 140
The laces just kept getting untied all the time (they're leather) as they have nearly every time I've worn them, which drives me crazy. So I finally decided, as I can slide my foot in and out without untieing the laces, to use some thin black thread around the knot to make them stay permanently tied (hard to explain, but I hope it made some sense) and it worked, yay!
