Review: Love it - I have been suffering with tight calves and knee pain,left leg,for some time.Had physio,etc,etc.,and noticed that when I stretched my affected leg backwards and as straight as I could without pain,my leg felt eased.On the basis of this,saw this item and decided to buy.On my very first time, gingerly carrying out the exercises that come in a pamphlet with the item,I noticed an almost immediate feeling of relief from the "tightness".I don't do the advanced exercise yet, slowly, slowly,but even walking up and down stairs is easier,no pain,no stiffness.I am so pleased I bought this and will continue with the exercises which take less than around half an hour daily.Very easy to use,well constructed,and has helped me enormously with my overall movement in practically no time.It's very effective and helped me so much.Definitely recommend. Review: Money well spent! - This is my first review on desertcart and it's a very positive one! I have had a nagging problem with my right Achilles, bottom of foot for some 3 or 4 months which has stopped my burgeoning running career!. There were various exercises suggested to me, such as hanging off the bottom of the stairs, or using a rubber band. They ma possibly have have worked if I had stuck to them but I didn't. However, I have been using the Medi-Dyne for a couple of days and I can honestly say that the improvement has been amazing and my foot/Achilles is now 95%, up from 75%. This product is so easy to use and, from my short experience, is incredibly effective. I am a bit of a cynic and probably would be sceptical if I saw this review written by someone else. However, I am totally genuine and I feel confident that thanks to this product I should be able to start running again within the next few days. ## Features - Rocker boot style maximizes stretching motion; provides gradual, even stretching - Heel plate prevents foot from slipping - Foot plate ensures proper foot alignment for most effective stretching - Mid foot gap allows ProStretch to be used as an ankle strengthening device - Rubber strips prevent product from slipping on multiple types of surfaces ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001HTFZZ8 | | ASIN | B001HTFZZ8 | | Age Range Description | Adult | | Best Sellers Rank | 44,690 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 562 in Foot Supports | | Brand Name | ProStretch | | Colour | Blue | | Customer Reviews | 4.7 4.7 out of 5 stars (799) | | Customer reviews | 4.7 4.7 out of 5 stars (799) | | Department | Unisex | | Global Trade Identification Number | 00038016000202 | | Included Components | Product | | Is discontinued by manufacturer | Yes | | Item Dimensions | 15.2 x 30.5 x 20.3 centimetres | | Item Type Name | Prostretch Double Foot Rocker - Blue | | Item Weight | 32.4 Ounces | | Item model number | S00020 | | Manufacturer | Medi-Dyne | | Manufacturer | Medi-Dyne | | Material | Polyvinyl Chloride | | Model Name | S00020_DF3 | | Model Number | S00020 | | Number of Items | 1 | | Part Number | S00020 | | Product Care Instructions | Hand Wash Only | | Product Dimensions | 15.24 x 30.48 x 20.32 cm; 918.52 g | | Product Warranty | warranty_description | | Size | Double | | Specific Uses For Product | gymnastics | | Sport Type | Walking | | Target Use Body Part | Foot | | UPC | 038016000202 | ## Product Details - **Age range (description):** Adult - **Brand:** ProStretch - **Size:** Double - **Specific uses for product:** gymnastics - **Use for:** Foot ## Images ![ProStretch Original Double Rocker Stretching System - Hamstring Achillies Calf & Foot Stretcher - Image 1](https://m.media-amazon.com/images/I/511IDhW3adL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Do I need to use the ProStretch Double while wearing shoes? Can I just wear socks?** A: The ProStretch Double should be used while wearing shoes with a supportive, rubber sole. **Q: What if my foot hangs off the ProStretch Double?** A: The ProStretch Double is intended for shoe sizes 12 or below. If your foot hangs off, that is absolutely fine. You are still able to obtain full use of the device even if it may look a little funny. **Q: Why is the ProStretch Double better than just normal stretching (e.g., on a wall, steps, or curb)?** A: The ProStretch Double holds your foot in an optimal angle, with a double rocker design, to get a superior stretch. **Q: What's the benefit of the ProStretch Double (bilateral)?** A: With the ProStretch Double, you are able to stretch both legs simultaneously and can use the opposite leg as leverage to deepen the stretch of the other leg. **Q: What is the difference between the ProStretch & the ProStretch Double?** A: With the ProStretch Original, you can only stretch one leg at a time. With the ProStretch Double, you can stretch both legs simultaneously. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love it *by A***R on 5 July 2025* I have been suffering with tight calves and knee pain,left leg,for some time.Had physio,etc,etc.,and noticed that when I stretched my affected leg backwards and as straight as I could without pain,my leg felt eased.On the basis of this,saw this item and decided to buy.On my very first time, gingerly carrying out the exercises that come in a pamphlet with the item,I noticed an almost immediate feeling of relief from the "tightness".I don't do the advanced exercise yet, slowly, slowly,but even walking up and down stairs is easier,no pain,no stiffness.I am so pleased I bought this and will continue with the exercises which take less than around half an hour daily.Very easy to use,well constructed,and has helped me enormously with my overall movement in practically no time.It's very effective and helped me so much.Definitely recommend. ### ⭐⭐⭐⭐⭐ Money well spent! *by O***! on 27 February 2016* This is my first review on Amazon and it's a very positive one!
