Open- toed I just adjust the bend in the toe but with an enclosed shoe I take the easy way out and hide the toes.

My procedure is to pose the figure and then apply the foot pose.  I spend a little time playing the dails for the feet and toes and sometimes the shoes.  If it is just the odd strap I tend to use the morph brush.  If i have to spend more than  10 - 15 minutes I give up and use a different pair of shoes but that is a rare occurance. 

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
