I have mixed feelings about Calden's invisible height increasing shoes for men. On the one hand, they certainly lived up to their promise to add 2.8 inches to my height. As a vertical caller, I can appreciate the momentum. Then again, these aren't the most comfortable shoes I've ever worn. The construction feels a little flimsy and they tend to pinch my toes after a while. I'll give credit where it's due though - these shoes are damn stylish. The premium black leather looks and feels great, and the slip-on design is comfortable. They are the perfect finishing touch to a formal outfit and I have received many compliments while wearing them. Overall, I would say that if you're looking to boost your confidence, Calden's invisible men's shoes are worth considering. Just be aware that you may be sacrificing comfort for added height.
