I should have addressed my foot drop when it first developed as I think walking poorly for years resulted in my needing a hip replacement and recovery from that has not gone well.
I’ve had an AFO (likely what is referenced as a splint above). This is the one that the specialist and I determined worked best for me but you should test several and see what style works best (they have different stiffness properties, etc.0 https://www.ebay.com/itm/Swedish-AFO-by-Alpha-Medical-Padded-Calf-Ankle-Foot-Orthosis-Foot-Drop-Brace/324218214435?hash=item4b7ce95823:g:9loAAOSw0-5e~uTt
There was also a little device that you can slip under your shoelaces and it hooks via elastic to a band that goes around your ankle a “toe up” type of idea that I found didn’t work at all and seemed to clamp down on normal ankle movement but I have seen others post a positive comment on them.
There are also some exercises that my PT guy recommended like walking on my heels. I found the AFO caused atrophy of my shin muscles and I should have been doing aggressive PT on them to offset but was just happy to be walking better and more and thought that would offset-
