    This is a great boot. Wide toe box. This is my fourth Z-CoiL Boot. I slipped a few years ago and my Doc said my working days were over. Z-CoiL has allowed me to keep working and walking. Before Z-CoiL I used a walking stick. Its an amazing invention.

    I work for the US Govt. and am on my feet all day. The prime boot is a great choice. I only use Z-Coil’s. I have 12 pair, 10 which are active. I have given up all my other shoes.

    My husband saw a colleague wearing a Z-CoiL boot at work many yrs ago, asked him about them. My husband can’t live without them! (literally he would be crippled and in bed, long story about his feet…) So, although they are a rather expensive tool, we can’t find a better substitute, and it keeps my very hard-working husband up and running.
    Thank You,

    i have owned what will now be 4 pairs of these boots. i have lots of “problems” with my feet such as chronic plantar fascitus made worse by fibromyalgia. these boots are the only shoes that EVER give me major relief. for about a year, they were unavailable. i spent a fortune trying to find substitutes. there were none. additionally, i have always won boots which are not only a fashion choice but also as a motorcycle and scooter rider a safety need. as of today with my re-buying these boots I am back to not only health but also safety. plus Cesar who own Z-Coil is the best!

    Because of many years working on concrete, working as a tester in the auto industry I started developing Plantar Fasciitis, I tried many other shoes and none of them helped with the pain I was experiencing, My sister recommended Z-CoiL to me and I have been wearing them for 10 years. I have 10 pairs currently. I wore the Prime Workboots all of the time until I wore them out each time, They are a great moderate level workboot. Z-CoiL’s have all but gotten rid of my Plantar Fasciitis, and I am able to continue doing volunteer construction work even though I am now retired. Thank you!!

    (verified owner):

    “I had a knee injury and was worried I could not go back to work. My pharmacist pulled me into her office and let me try her Z-CoiL’s. The Z-CoiL’s changed my life, and I can even run again at age 60. I now run circles around all my co-workers. I tell everyone I know about Z-CoiL’s. “

    I would rate them excellent 5 stars in terms of comfort and solution to my plantar fasciitis but very low on style and design.

    I own two workboots,love your design for the shock absorbing coil, and that the heels are replacable.

    When it comes to knee pain relief…Z-CoiL’s are NUMBER ONE!!! After two surgeries on my left knee…they are not simply “nice”…they are “NECESSARY”!!!!!

  11. 5 out of 5


    With terrible feet problems and having to stand for work most of the day, it’s like having shock absorbers for the body and really help me get through the day.

    Wonderful shoes! A little expensive… my knees don’t think so. Wish they had stores in the Northeast.

    The work boots are the most comfortable shoes I have ever worn and great for hiking.

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
