I decided to upgrade them....
I found some suede scraps that has been lying about after another project and I decided to use them to make new straps and soles.
I've removed old straps and insoles, and removed diamante details. Copied all pieces on to suede and cut new pieces to replace the old ones
Here are the new suede piece covering insole and
new straps are doubled and stitched to form new straps
Then diamante detail is stitched on to the straps and attached the toe post piece and decorated straps are attached to the insole
beautiful and comfy as suede is real and feels
much better than before. I am very happy with my new sandals
