When choosing modern shoes for use with slot cleats look carefully at where the seams on the sides of the shoes lie in respect to where the strap will cross over the foot. Shoes designed for straps and cleats don't have any seams where the strap crosses over because the tightly tensioned strap will, with miles and time, wear away the stitching causing the seam to open up.
