Another celebrated company that can be named is Rainbow Sandals.

Rainbow Sandals
Jay Sparky, the owner of Rainbow Sandals Inc. started producing and selling six pairs of hand-made sandals in 1972 in a small garage.
He bought the materials by himself and made sandals all by hand. Then he gradually increased the number of pairs and finally, his brand was established in 1974.
His company has been enlarged, by the year 2000 it could be producing two million pairs a year.
Now Rainbow Sandals Inc has become a star company all around the world.
As was discussed, Rainbow Sandals Inc. is one of the top factories that make high-quality sandals with a huge degree of comfort.
There is a lovely quotation by Jay Sparky, the owner of Rainbow Sandals Inc.
that says: “We are interested in receiving letters from people who write us about our sandals and their experiences they walk on with.
All Rainbow Sandals’ customers say they love their goods, and we hope you love them too”.
A very smart humanitarian program was run in the company under the title of “repair, reuse, recycle” around 40 years ago.
In those times, Jay found a sandal that had been left like trash.
He took it to his garage and try to repair it.
He himself says that the process of the repair-reuse-recycle program took a lot of time due to some reasons.
He had to formulate glue for fixing the sandal, formulate a sponge rubber to put in it to make it usable, and other things such as finding the best-needed fibers, using necessary items for sandal pieces to hold them tightly together, etc.
After doing all these steps, he donate the repaired sandals to poor people, homeless guys, and victims of disasters like wars, tsunamis, earthquakes, and so forth.
On April 29, 2022, Rainbow Sandals donates a hundred pairs of this program to Ukrainian refugees through a non-profit organization, NGO.
