This is usually the result of a slow arm swing. You can get some rubber bands and put 5 together. Slip one of each of the 2 sets of rubber bands around your shoe then with wrists down pull each of them up to your ears very quickly . This will increase your arm swing. Also make sure you are doing core exercises for the inner core like planks, bird dog etc. You can also use water bottles and lie down on a mat and swing them up and down as fast as possible. Usually what is happening is that you don’t get the arms all the way up and you are still going forward thus the landing on the toes. Also make sure you are strong in your glutes and hamstring area.
