Squeaky rubber soles in tennis shoes
A quick shout-out to the guy who posted a squeak fix using oil and a injectable needle. I gave it a try but did not work for me. However his solution inspired an alternate solution.
#1 First you need a drill and a WD 40 nozzle tipped can
#2 Drill in the in-step; 3 holes about an inch apart.
#3 Insert tube and do a quick spray in each hole.
#4 Repeat same on opposite side.
#5 Walk around the house; then go back and repeat 2,3,4
#6 Worked like a charm. No more annoying squeaking.
NOTE: I believe this type of squeaking is caused by washing your tennis shoes or exposure to deep water, when a small amount of moisture gets trapped between the parts of your shoe and sole that are molded together. A little WD 40 does the trick!
