It's Zubao brand foot sweat deodorant, a white powder that can be directly sprinkled into shoes to treat foot odor. Husband's feet stink, so he should wear leather shoes to work. After taking off their shoes at home, the whole family smells like smelly feet. After good measures, the effect is not good. Finally, it was treated with Zubao brand deodorant for sweaty feet. The effect of this medicine is really unusual. On the first day I bought it, I sprinkled it in my husband's shoes and took off my shoes at night.
