Where's the 1st Marker?

Knitting Rainy Day Socks and about to knit the toe. Unfortunately, I lost my markers along the way. Not a huge deal as I had all my instep stitches on one needle and rest on another. Problem is that I need to know where my markers are for toe decreases. Does anyone know how many stitches before the instep stitches begin that the marker is supposed to be???

Thank you.

With the socks I’ve knit it on two circs the markers aren’t really important because the needles themselves work as markers. You decrease one stitch in at either end of each needle. Check how the decreases are on your pattern and don’t worry about the markers if you’re using two circs.
