I think we are looking for the same thing!!! I have trainers, sandy's & ME side snapping AIO OTW.
I have a stash of tots bots minky. This morning I just tried stuffing the tongue of the inside into the pocket opening & putting the aplix on & pulled them up on my son. I need to let him try pulling them up & down on his own but it worked ok. I needed to tighten them once they were on.
What about ODC loops? It is a side snapping fitted.
