Take off those grocery getters platform and you may find it easier to click in and out. When you get on the bike get off the saddle and push your foot down, it should click fine and then do it with the other foot. Practice makes perfect. After you get the hang of it try and reattach the platforms if you want, but if you have a mtb shoe you should be able to walk around in them enough to warrant putting them on even for quick trips.
