Let me be honest with you. I'm 5'8". For most of my adult life, that felt like enough. Until it didn't.
It wasn't about being short. It was about the moments where height quietly matters — and nobody talks about it. Walking into a job interview next to a guy who's 6'1". Standing next to a girl you like and realising she's looking slightly past you. That first handshake where you immediately feel like you're playing catch-up.
I started looking for a solution. Not elevator shoes — too obvious, too expensive, too much of a commitment. Something simple. Something that works with what I already wear. That's when I found ExtraCM.
What Are They?
ExtraCM Soft Pro are height increase insoles — but not the cheap foam blocks you've seen before. Engineered with three distinct layers that work together to give you a real, comfortable lift of up to 7cm. Completely invisible once inside your shoe.
-
✓
TOP LAYER — Breathable mesh that eliminates heat and odour even after 8 hours of continuous wear.
-
✓
MIDDLE LAYER — 18 independent Bio-Align Pod System air chambers. They redistribute your weight, correct your posture and absorb impact with every step.
-
✓
BASE LAYER — Structured EVA with ribbed channels. Ground impact absorption and height elevation: +3cm, +5cm or +7cm.
-
✓
WEIGHT — Just 78 grams the pair. You genuinely don't feel like you're wearing anything extra.
The three-layer Bio-Align Pod System — mesh, cushioning pods, structured EVA base.
I've Been Wearing Them For 6 Weeks.
Here's what actually changed.
The obvious one: I'm taller. Not dramatically, not in a way that looks fake — just taller. The +5cm model is what I use daily. It fits perfectly inside my Nike Air Force 1s and my Chelsea boots. Nobody has ever looked at my feet and thought anything was different.
The less obvious one: my posture. After a week I noticed I was standing differently. Shoulders back, spine straighter. My lower back — which I'd had issues with for years from sitting at a desk — felt noticeably better.
The least expected one: how people respond to me. Studies show that taller men are perceived as more authoritative and more confident before they even say a word. When you stand taller, you feel more confident. It's a feedback loop that starts from the ground up.
I never thought 5cm would make a difference. It makes a difference.

What Real Customers Are Saying
"Bought the +5cm for a work trip. Wore them in my Timberlands for 3 days straight. Nobody said anything but I felt completely different. Worth every penny."
"I was sceptical. I've tried cheap lifts before and they're uncomfortable after an hour. These are different. The cushioning is real. Two months in my Jordans and still going strong."
"Game changer for dates. Simple as that."
