Review: My old family Dr. recommended - I’ve been wearing the Spenco 3/4 inserts for almost 20 years if not longer. I’m flat footed and had been experiencing foot pain starting in my early twenties….shortly after my arches fell. My doc told me to try these but at the time they costed more than I wanted to spend. So I ignored his recommendation. When I finally decided to try insert, I went and purchased a different brand some from the local pharmacy because I wasn’t shopping online 20 years ago. Those things hurt sooooo bad I swore against them. After another year of dealing with the pain of flat feet, I decided to go ahead and order from the website my Doctor had originally given me. When I received and began wearing those Spenco inserts, it changed my life. They helped alleviate foot, back, shoulder and headache pain. Just that little tweak in alignment starting at the feet help shift so much in my upright posture. Afterward, I didn’t care about the cost and so I ordered 3 more pair… 2 for me and one for hubby. I put the in all my regular/daily shoes and would swap them into my not-so regular shoes when I’d change shoes. When my kids became teens in track, basketball, volleyball and soccer, they also needed the support of the Spencos. Now they are adults and just like me, they are sure to have a pair or two on hand. Review: Great insoles! - These are amazing. They Work for plantar fasciitis. The arch can be molded with heat (usually at the podiatrist office they adjust them). For me, they fit in most of the shoes even with my chubby feet. Sometimes you have to remove the shoe insole and replace it with this one to get extra space. ## Features - 3/4 length replacement arch support insole with a thin profile for dress or casual shoes and boots which provides complete heel-to-toe comfort - SpenCore cushioning layer absorbs shock and impact to provide lasting comfort for flat, low or fallen arches - Thin orthotic shell provides stability without the added bulk of most orthotics - Firm adjustable arch support allows for greater arch support when heated and molded to individual preferences - 4-way stretch fabric helps prevent blisters - Moldable Arch Insert The flexible plastic arch insert helps support and control the foot ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0012S7IVI | | Best Sellers Rank | #52,728 in Health & Household ( See Top 100 in Health & Household ) #417 in Shoe Insoles | | Customer Reviews | 4.4 4.4 out of 5 stars (1,164) | | Date First Available | August 26, 2004 | | Is Discontinued By Manufacturer | No | | Item model number | 43-240-02 | | Manufacturer | Spenco Medical | | Product Dimensions | 8 x 3.31 x 0.8 inches; 3.68 ounces | ## Product Details - **Brand:** Spenco - **Color:** Clear - **Material:** Plastic - **Product Benefits:** Arch support - **Use for:** Foot ## Images ![Rx Thinsole 3/4 Length Shoe Insoles, Women's 7-8.5/Men's 6-7.5 - Image 1](https://m.media-amazon.com/images/I/81LhB7Ij6QL.jpg) ## Questions & Answers **Q: If I wear a half size, should I go up or down?** A: Let's say you wear a Men's 7.5 - you would want to select the next size up (Men's 8-9). By selecting the next size up, you ensure the inserts will accommodate the width of your foot and proper arch placement; you might find that the size down is too narrow or that the arch is out of place. **Q: How long do these last? i wear them 3-4 days a week.** A: I wear mine 5 days a week ,averaging 8000 to 12000 steps per day.. not positive , but i believe I have had mine about 5 years( msyby more ) . I have insoles for each pair of shoes **Q: What does "moldable" mean in the description? I don't see any instructions on how to do mold it. Thx** A: i think it means it can be professionally molded with heat. my podiatrist has me buy then and to bring to him for adjusting for my foot. i haven’t had my appointment yet. **Q: I bought the wrong size - I need to get a new - how do I exchange?** A: Amazon should have instructions on how to return product to seller. ## Customer Reviews ### ⭐⭐⭐⭐⭐ My old family Dr. recommended *by M***C on January 27, 2025* I’ve been wearing the Spenco 3/4 inserts for almost 20 years if not longer.

My Nike tennis shoes had almost no arch support, so I got these after a recommendation. They are comfortable, fit in my shoes, and provided great support. The only con would be that they made my shoes squeak for like a month. I guess I wore them in enough that they don't squeak anymore and I didn't care enough to replace them. Overall, these are great insoles and I doubt that they will make everyone's shoes squeak, so I wouldn't let that dissuade you from getting these. ## Frequently Bought Together - Spenco Rx Thinsole 3/4 Length Shoe Insoles, Women's 7-8.5/Men's 6-7.5 - Spenco Rx Orthotic Arch Support 3/4 Length Shoe Insoles Women's 7-8.5/Men's 6-7.5 - Spenco Rx Orthotic Arch Support Full Length Shoe Insoles, Women's 7-8.5/Men's 6-7.5 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/4656858-rx-thinsole-3-4-length-shoe-insoles-womens-7-8](https://www.desertcart.co.th/products/4656858-rx-thinsole-3-4-length-shoe-insoles-womens-7-8) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-28*
