Here's a free skate shoe PSD mockup. This 'fresh kicks' mockup has editable smart object mockups where you can drop your pattern or design for a simple one-click design. There are also editable layers where you can select flat colors for the different shoe panels, laces and soul.
This is one of my older mockups before I really figured out layer masks, but it's still really easy to use.
Feel Free to use this in your personal projects with attribution and contact for any other use.
As always, I would love to see what you're working on or designing, so feel free to reach out or connect with your finished design. Thanks!
