Did you scale Aiko's shins? If so you need to scale the boots shins as much. Usually if you scale shins longer the shoes/boots wont fit very well, especially if you bend the things. Sometimes deleting Thighbones from the boots/shoes helps but not allways. I wouldn't recomend it either but thats what I do. I delete all the "extra" bones (hip, abs chest and all the bones that are not assigned to the figure) from the conformer and it sometimes solves the problem. Or alternatively, you could turn of bending from the thigs and hip from the boots.
