While your old gym shirt works when buffing your shoes, it certainly doesn't work well. Its looser weave is prone to leave streaks, lint, and wax buildup.
If you're looking for that mirror shine, we'd suggest upgrading that old shirt to the FootFitter Professional Microfiber Shoe Shine Cloth. These premium shoe shine cloths are tightly woven that thoroughly buffs away shoe waxes and polishes thereby eliminating the possibility of streaks or unwanted buildup. And, thanks to its microfiber construction, you will achieve that final shine with not a speck of lint in sight.
FootFitter Professional Microfiber Shoe Shine Cloth is 20.5 inches in length, allowing for a full arm extension when buffing. Get the best shine possible with the FootFitter Professional Microfiber Shoe Shine Cloth.
