CastleFlexx is a collection of patented health and recovery inventions. USA Made. USA Owned. Established to heal in 2022.A note from inventor Dan Castle:My goal was to change how chronic pain was being treated.This would require that I design a solution which could achieve1) Toe Dorsiflexion since the plantar fascia activates the entire posterior chain when its pulled back and engaged unlike with straps and bands which leave the muscle groups in the leg inactive2) Relaxing natural grip for longer stretch sessions, no more rope burn please!3) A more practical, convenient, and financially responsible solution that would target the ROOT cause of the chronic pain.I began testing Castleflexx and after just a few days everything changed for me. I felt a release in my back I hadn’t felt before. Shortly thereafter, I felt noticeable improvement in many other areas. For example, I stopped getting plantar fasciitis completely. GONE. After a few months of using CastleFlexx for 8 to 16 minutes a day, I began to feel better, move better and even look better. My wife Carly, who had also begun using CastleflFlexx, experienced significant improvement and no longer complains about her hip pain and sciatica. Life just got better for both of us.I hope our device which has a less than 2% return rate and is made in the USA helps you too!Dan Castle

Fast, fair, and courteous support but more importantly and amazing product. Very high quality and easy to use, makes stretching fun and effective. The heat is nice, but a bit hot for a longer strentch (5 mins or more). Wish it had levels, but it’s convenient to turn off during a stretch. Last point is sizing, if your flexible, you need less length which can offset your height.

There are similar products out there, but they can't compare with everything the Castleflexx offers. First off, the added weight at the handle makes it a lot easier to roll and leverage. If it's too much, you can take it right off. The full width of the fabric makes the biggest difference in your stretch because it pulls your foot back to the correct position. The competition doesn't offer this on their products. The fabric is so durable and strong, you don't even have to worry about anything ripping. There is an alignment print on the bottom so you can align your foot properly on the underside of the fabric. The handles are made well and they absorb moisture so you don't slip at all. You get helpful paperwork with the items and there are so many online resources to use. The stretches you can do with this are so unique and, collectively, you can't do all the same stretches with another product. You get an all in one device to cover all the parameters you need for stretching. Your hamstrings will thank you for this! I had to reach out to the customer service a couple of times for inquiries I had about my order and product information (not issues they created). They were nothing short of amazing, and I was pleasantly surprised with how well they service their customers. I wasn't sure what to expect and I was taken aback with the quality of their team!

Thanks for the detailed review, Adam. You hit the exact things we obsess over - the weighted handles, the full-width fabric, the alignment print. And I'm glad the team took care of you when you reached out. - Daniel A. Castle
