The 18-year-old model is naturally seven inches taller than her 5-foot-3 sister, but a pair of woven Balmain booties helped her reach new heights on Wednesday.
Jenner poked fun at Kardashian's diminutive stature later that day on Instagram.

Jenner has continued her modeling work at Paris Fashion Week, and walked the runway for Chanel on Tuesday.
