Also you could try to download txt files with footprint corners coordinates located here: https://ladsweb.modaps.eosdis.nasa.gov/archive/geoMeta/6/TERRA/
File example: https://ladsweb.modaps.eosdis.nasa.gov/archive/geoMeta/6/TERRA/2018/MOD03_2018-01-01.txt
*Python 3 Code to convert .txt MODIS footprints to ESRI shapefile (as @mikoontz requested). QGIS 3 required.
Disadvantage: 180 degree meridian problem does not solved.
