Review: Affordable, comfortable, & stable - As a senior citizen I noticed I've shrunk an inch or more & wanted to get back to my 5'10" height so these insoles did the trick, are comfy & no one notices the increase
Review: These Height Increase Insoles WORK! - I recently tried the CALTO IK302 Height Increase Insoles, and overall, I’m quite satisfied with their performance. Here’s a breakdown of my experience: Comfort & Fit — These insoles are surprisingly comfortable for a height-increasing insert. The E-TPU technology, often referred to as “popcorn rebound,” provides a good amount of shock absorption, making them easy to wear for extended periods. They have a lightweight feel, which is great because some elevator insoles tend to feel heavy or clunky. One thing to note is that they work best in high-top sneakers, boots, or roomy shoes. If your shoes are already snug, these may make them too tight. Height Boost & Stability — The 1.4-inch (3.5cm) lift is noticeable but still natural-looking. Unlike some height inserts that feel unstable or wobbly, these provide decent balance and support. That said, they don’t have arch support, so they might not be ideal for people with flat feet or those needing orthopedic support. Durability — The E-TPU foam material feels durable and retains its bounce well after multiple uses. Some foam-based insoles tend to compress over time, but so far, these have held up nicely without losing height or cushioning. Pros & Cons ✅ Pros: • Comfortable and lightweight • Good shock absorption • Natural height increase • Durable material ❌ Cons: • Works best in shoes with extra space • No arch support • Might take time to adjust to the added height Final Verdict — If you’re looking for a subtle yet effective height boost, the CALTO IK302 insoles are a great option. They provide a good mix of comfort, durability, and natural lift, making them a solid choice for casual wear. Just ensure your shoes have enough room to accommodate them for the best experience.

## Features

- ✔Max 1.4" height boost: Occupies more room in your shoes but provides the most elevation when inserted. Best to be used for high top shoes or boots with a high shaft.
- ✔Discrete & Versatile: Completely discrete and unnoticeable once inside your shoes.
- ✔Things to consider: Your foot may need time to adjust to the incline over a period of few days or so. Instant height increase can cause foot pain. Most users find that they slowly ease their way into the height increasing insoles, they achieve the best results. Other differences from regular insoles may include: Minor reduced stability, increased pressure on ball of foot, shrinking size.
- ✔Weight: 2.3 oz. *Actual weight varies.*. Extremely light weight, you won't even notice them on foot.
- ✔Main Insole Height Increase: 1.4" (3.55 CM).

### ⭐⭐⭐⭐⭐ These are very cushy
*by S***M on June 30, 2023*

These Height Increase Insoles E-TPU Technology Popcorn Rebound Shock Absorbant insoles are great. They are cushions as well as "height increase". I got them for 2 reasons. 1 - Due to an accident, my ankle is fused in a specific position. I HAVE to wear at least a 1" heal. Right.... Find athletic shoes with a 1" difference in height between the heal and toe. If you can, they are wicked expensive. 2 - I stand on concrete 10 hours a day. If I don't have some kind of cushioning for my feet, I can barely walk at the end of the shift. These insoles solve both problems. They provide the extra heal height I require, and still provide cushion for both the heal and the balls of the feet. My only issue is that they only come in a 1.4" height. A 1" height would do the same thing for me, but fit better in my work shoes. I still highly recommend these Height Increase Insoles E-TPU Technology Popcorn Rebound Shock Absorbant insoles.
