Since there are many manlets on here, I thought you might be interested in pic related.
Here's a video too: https://www.youtube.com/watch?v=Ker2QwWWquo
I'm don't sell them or anything, and I don't use them since I'm already naturally tall.
These are stupid and for insecure fuckwits
There's a brand I think is called Taller that sells shoes designed to increase your height, marketing on the idea that manlets "can get da grills" and it being embarrassing for a guy to be shorter than a grill.
Plus, you don't want inserts unless you need them. I actually have orthotic inserts to help with my arthritis, they suck because they limit the kind of shoes you can wear. Its usually not a big deal with sneakers, I'd say around 70% have removable footbeds but finding boots sucks and formal dress shoes never work, so I'm forced to suffer whenever I need to wear them. There are brands that cater to people who need removable footbeds, but they almost always have the ugliest looking shoes (Think hybrid sneaker/dress shoes with big soles and hideous design)
Lets be honest, girls put on 4" in heels that add to their height. If youbare an average guy that males the girl taller than you by at least an inch.
The 1.5" is a good choice for this, more formal, situations.
