So Kate 120: real vs fake
The So Kate 120 is the most recognizable Christian Louboutin pump: a 120 mm ultra-thin stiletto with an extremely pointed toe and a low-cut vamp. That aggressive geometry is exactly what replicas get wrong – factories almost always miss the toe pitch, the foot pitch and the build quality.

What to check on the So Kate 120
Model-specific zones – on top of the brand-level signs.
Red sole shade
The shade of red varies between authentic pairs: these are handmade shoes from different factories, with different batches and materials, and on worn pairs a cobbler often re-lacquers the sole in his own red – camera white balance shifts the color further. So the shade is not a verdict: look at the nature of the coating (lacquer, not rubber or paint) and at how cleanly the edge is finished. A warm tone on its own does not make a pair fake.
Sole printing
"Christian Louboutin" and the size are stamped into the sole in a clean, even font in the correct position – replicas show a font that drifts, uneven letter weight, or misplaced text. On a new pair the heel tip is red, but heel taps are a consumable: replaced black or beige taps and a protective sole guard (which hides the printing) are signs of servicing, not of a fake. Judge the printing only if it has survived.
Pointed toe and low vamp
So Kate is defined by an extremely pointed, elongated toe and a very low vamp cut that exposes the instep. A rounded, short, or high-set toe box signals the wrong model or a fake.
120 mm stiletto
The So Kate heel is a true 120 mm ultra-thin stiletto with no platform and a steep foot pitch. A thicker, shorter heel or a hidden platform under the last points to a counterfeit.
Insole and branding
The insole carries "Christian Louboutin … Paris" in the correct font with a crisp logo. The country in the stamp depends on the model and the year: authentic pairs come as Made in Italy, Made in Spain and Made in EU (men’s sneakers after 2012 are usually Made in EU). The worry is not "a different country" but a run-together "MADEINITALY", the wrong font, wrong letter spacing and crooked embossing.

FAQ
The red sole scuffed after a couple of wears – is it fake?
No. The Louboutin sole is genuine lacquer, so it scratches and wears down when you walk – that is normal for an authentic pair, and Louboutin even sells sole protectors. The suspicious case is a "bulletproof" matte red that never scuffs.
How do I tell So Kate from Pigalle in photos?
So Kate has a sharper, longer toe, a lower vamp cut, and a noticeably steeper foot pitch at the same 120 mm height. The Pigalle looks slightly softer in toe geometry.
What is the correct So Kate heel height?
The classic So Kate 120 is a true 120 mm ultra-thin stiletto with no platform. A 100 mm version exists, but a claimed 120 with a thick or shortened heel is cause for suspicion.
