Hi - like @njed, I have idiopathic PN (6 yrs) and have a bit of a dropping of my left foot. I’ve been fortunate to not have fallen, but the feeling of toe dragging has caused me to come close to tripping several times. For Me it seems to have correlated with the slight “curling” of my middle 3 toes on that foot, I guess the start of hammer toes, surely part of my PN. @johnbishop has posted some information on this subject if it might apply to you, and this group suggested some inexpensive toe support products that seem to be helping. However the main thing I had to work on is getting my brain trained to help me develop a step pattern to make walking safer. For me, even changing into a different style of shoes is a drain on the brain to change, but on the most part, with help from physical therapy too, I’ve learn to walk more safely with my foot issue.
