So, this design embeds the spikes into the platform of the shoe.
After marking out the placement, I drilled the holes and reamed them to fit a stud.
Next, I filled the holes with epoxy (oops, some of them were way too deep) and set the studs in place with the screw back only partially screwed. This allowed epoxy to get around the stud for a better hold (I hope.)
I’ve learned for next time to definitely use a depth gauge for drilling and make sure I have an application nozzle for the epoxy. My plastic baggie method was a mess! See the drops of glue staining the suede?
A catwalk around the house reveals the studs do not catch on the carpet and my feet have swollen this winter.
