One foot toe walking???

Torie • God is #1 in my life <3

My 14 month old has been walking since she was 12 months. Today I noticed she has been walking like normal, but with her right foot on tippy toes. her left foot stays flat, but the right one on toes. She doesnt do it constantly but enough to where ive noticed it and am concerned. Can this be normal or what is she doing??
