Kourtney Kardashian Hoarding A $400K Boot Collection!

Kourtney Kardashian is finally investing in something other than her brood

— a massive collection of sexy thigh-high boots!

“Kourtney has well over 350 pairs of boots and at least 50 of them are thigh-high,” a mole dished.

“All are designer, so you’re looking at a boot collection worth nearly $400K!”

Most of the boots given to the 38-year-old were gratis —

and luckily for her sisters, whenever they feel like struttin’ their stuff,

they’re welcome to borrow them anytime they please!

“If they start to look worn, Kourtney will just get another pair or two.

She loves the over-the-knee boots the best. They make her legs look long,” the tipster revealed.
