The mixed six-pack refuses to guess: three tubes of each tint means the white trainers, brown boots and black work shoes all get a matching repair from the same box.
Buying one tint is a bet on which shoes fail next. The mixed box retires the bet — whatever lets go, light or dark, the matching tube is already in the drawer.
Households consume the tints at roughly equal rates: black for soles and heels, clear for seams, uppers and coatings. Symmetric supply matches the real workload.
A family’s footwear is a mixed fleet — school shoes, site boots, weekend trainers, rain gear. This is the one box that services all of it without a second order.
Six sealed tubes is a multi-year horizon for most homes. Stored cool and opened one at a time, the box quietly outlasts several generations of the shoes it repairs.
One clear, one black — the two-tube set that matches whatever shoe fails next.
The top-rated clear pair — two flagship tubes, one for now and one so there is never a gap.
