There are lots of products to help foot drop. As Jen said, you should enlist the help of a physiotherapist who can help you with exercises, refer you to different providers of solutions, and/or get you supplied with devices to help.
The solutions range from fairly basic additions to your shoe: https://www.ossur.com/injury-solutions/products/foot-and-ankle/ankle-foot-orthosis/foot-up or http://www.orliman.com/en/product/calf-support-for-the-boxia-drop-foot-ankle-brace/
Or there are orthotic devices or braces for which you might be referred to your hospitals Orthotics Department.
Or you might be able to get a Functional Electrical Stimulation (FES) set up. Have a look at https://www.mstrust.org.uk/a-z/functional-electrical-stimulation-fes The most common is What is FES? | Odstock Medical Ltd (OML) Some areas do not fund FES on the NHS. Where I live (West Sussex Coastal) is such a Trust.
You’ll find that if you continue to walk without an aid with foot-drop, you could end up hurting various muscles as your step pattern is badly aligned. Some people end up ‘hitching’ their hip as they try to pick up the unruly foot, or swinging that leg round in order to avoid stubbing their toes. Either way, you risk hurting your hip.
Best of luck finding the right solution for you.
