    I have had leg and back issues for years and have tried pretty much every over the counter option and even a insert made for me by a doctor. A year ago a friend recommended these shoes and after a year of wearing them I can honestly say these shoes are the biggest help I’ve ever had both at work and at home and will probably never buy a non-zcoil again.

    These literally changed my life. After a while my first pair of work boots got me pain free from plantar issues. Now, very rarely have any issues and they are very comfortable.

    I love Zcoil shoes. I have planter fasciitis and low back pain. I walk or stand on concrete all day at my job and if it weren’t for zcoils I don’t think I could still be working.

    These are the only shoes I can wear and not have my feet hurt. Please bring back the pull-on boots, I used them for dress shoes. You don’t really have much to choose from for dress wear. I’ve had several pairs of them in the past. I have a pair of the casual shoes.

    My favorites are the pull-on boots you no longer carry. I wore them any time I wasn’t working. They were a little dressier than the hikers. Please bring them back.

    I was skeptical at first but I really needed relief from chronic back pain. My work requires sometimes long hours on my feet on concrete. Worth every penny ! I need all the help I can to get through the day and these boots not only provide a very comfortable walking or standing experience they provide great ankle support.

    These shoes last longer on the “hurt floor” then my regular hospital type shoes. They help curb the pain from being on the floor for those “never ending” long hours.

    I have dealt with back pain for 40 years due to a head-on auto collision. The Z-coil shoes minimize the stress my back sustains during a work day which relieves muscle stiffness and subsequent pain.

    Great durable work boots! I have very high arches and the zcoil adjustable soles fall short that’s my only complaint!

    I would buy a size 15 prime workboot for my brother-in-law if you made one.

    “I work on hard surfaces all day long and it was getting to where I was taking the daily max of OTC painkillers just to make it through an 8 hr shift. Then I happened to see a guy wearing these crazy looking shoes with springs in the heels, one day. I ask about them and he told me to Google “”Z-coil.””
    That was 3 years ago and now it’s the only brand of footwear I’ll ever own. Z-coil literally saved my job.
    They’re expensive and ugly, like a divorce, so you know they’re worth it! “

    The boots wear out rather quickly and we seem to always have to buy a new set of heels for each pair glad to see the last pair came with them! I have had trouble with the workmanship of a couple of pair and had to glue them back together several times! In fact I need a new pair for a different pair of boots will order soon! Have had to glue the sole back on to the tennis shoes twice!

    My knees were giving me an issue because I am walking between 4 and 6 miles on concrete daily, I would be limping around by the end of the day and by the week-end I wouldn’t go anywhere so I could let my swelling in the knees subside. Then on Monday I would start the process all over again. The Z-Coil shoes have made a huge difference by reducing the force of the impact on my joints, which has allowed me to walk normal all day, and look forward to doing things on the week ends again.

    I still can’t believe there exists a comfortable steel-toe boot.

    “After my husband’s very successful back surgery he still had foot pain working on concrete and asphalt, while out shopping with me or working for Road and Bridge. I suggested trying a Z-coil boot. When we found a workboot with composite toe and and an enclosed coil, it was off to Denver (a 5 hour road trip) to have him try on a pair. HE LOVES THEM and wants another pair in a loafer type style.
    DRAWBACK: Denver is a long way to try on a pair of shoes, but the service we have experienced with Z-coil over the phone leads me to believe that we could order his size and if it didn’t fit he could return or exchange it without a big hassle.
    Now I need a pair and need to get my mom a pair, as well.”

    I have been using Zcoil for about 8 years. I need them for my back problems, I would not be able to walk very far without them.

    The best work boot ever! I have had these Z-Coil work boots for over ten years now. I had feet pain because I work on concrete all day. My friends always ask me where do I get these boots. The only downside is that Z-Coil always sells out on my size 12 boot composite toe workboot and they don’t stock enough. Thank you Z-Coil for making my feet pain free!

    Boots have helped a lot . Wish u had half sizes though. Just about cured my extreme Planter Fasciitis.

    I have been working in these boots for over a year and I love them! They are awesome for working on concrete everyday!

    I work on my feet nearly everyday – most often in industrial and construction zones.
    I not as young as I used to be and every little bit of foot stability and support helps.
    So far, Z-CoiL’s have the edge in this market for now.

    I had foot fusion surgery. I couldn’t find a boot to fit me, the ankle was to wide to fit in most other boots. I had a walking boot on for a year. Thought it was going to be on forever! My heel had a lot of pain. I bought the prime work boot, at first try my foot fit the boot, I thought alright, then when I first stood up on them I felt little off balance but after I got used to using them its ok. Now the pain in my heel is gone when i’m walking.

    I bought these for my husband, He loves the comfort the boots provide while he’s working all day the only complaint he has is that the leather on the front of the boot tends to wear out a little faster than the rest of the boot other than that Love the Boots. Thank You!!

    I haven’t met a Z-coil product I haven’t loved. My husband nearly had a coronary when he saw the price tag of my first pair of sandals. He quickly changed his tune when he saw how they increased my mobility and how much more I was able to help him. When it came time for a new pair of work boots, I didn’t take much to talk him into a pair of these boots. That was 2010. Well, at the end of 2014, he is finally wearing them out enough that they need to be replaced! Thank you for such a great boot that meets our PPE requirements, but are comfortable and wear like iron!!

    I work construction, and hate my Steel toed boots. I tried this Prime CT and LOVE them!!! Good thing I fit into a mans size, cause they dont come in womens sizes.
    They feel great while on the job, the only thing is the heel sticks out a little so some of the guys on the site can tell they’re not regular shoes, and they laugh at me.
    But it’s ok, my feet and back feel A LOT better than theirs!!!!

The Prime Workboot was built specifically for those whose work required a boot. It runs slightly wider than our Freedom Classics. The shoe is built for a normal E width but because it is a lace-up, it can be adjusted for all widths C through EE. We built the toebox (ball of the foot) to a E width to prevent irritation in this area This shoe runs true to size so order the size that you normally are. For unknown size, measure your foot length on a ruler and use the size chart below to find your size. This shoe is ergonomically designed with our standard great fit features: -a rounded heel, - a built in orthotic with a standard arch, -a wider than normal toebox width for better fit in the toe area -a padded tongue and collar for decreased abrasion -a rocker bottom for easy mobility -conical spring in the heel for 50% impact reduction to the body -speed lacing on top -above the ankle support Womens size conversion chart Mens size conversion chart
