Ongoing foot discomfort can make every step feel heavier and more tiring than it should. Over time, even simple routines—walking to your car, climbing stairs, or getting out of bed—can start to feel like challenges.
That’s why many people explore different options—store-bought insoles, ice packs, stretching routines, or professional care. Yet, the discomfort often finds a way to return, interrupting activities and limiting comfort.
That’s where the Koprez CustomFit Insoles come in.
They’re built with ThermoFit™ Core technology, which molds to your unique arch and heel in under five minutes—just heat, stand, and they adapt effortlessly. No two feet are the same, so a custom fit is crucial. The process is effortless, the relief is quick, and the result is a one-of-a-kind insole that supports your natural shape. Unlike store-bought insoles that flatten over time, ThermoFit™ keeps its shape, delivering lasting comfort.
By wearing the Koprez CustomFit Insoles regularly, many individuals have shared that they experience improved comfort and greater ease in their everyday movement.

Instead of just telling you about the benefits of the Koprez CustomFit Insoles, here’s a message from one of our customers, Jennifer:
“I’m constantly on the move between school runs, grocery shopping, and keeping up with my kids’ endless energy. Before, my feet would start aching halfway through the day, and by the evening I could barely stand without discomfort.
What surprised me most with the Koprez was how easy they were to mold. Just a few minutes and they shaped perfectly to my feet. The very first time I slipped them into my shoes, they felt like they were made for me. The custom fit really supports my arches and heels in a way I’ve never experienced with store-bought insoles.
Now, I can get through a full day of errands, standing in long lines, and even family outings without that familiar soreness creeping in. Walking feels lighter, and I don’t find myself constantly looking for a chance to sit down and rest.”

Yes, Koprez® CustomFit Insoles are designed for individuals across various age groups. Foot discomfort can affect people from all walks of life—whether it’s an athlete looking for extra support during training, someone on their feet all day at work, or an older adult wanting added comfort for daily activities. These insoles can help support everyday foot comfort.
Can I use the insoles with any shoes?
Yes! Koprez® CustomFit Insoles are designed to fit into most types of closed footwear. Once customized to the foot’s unique arch and heel shape, they sit securely inside the shoe without adding bulk.
Can I move the insoles between shoes?
Technically yes, but each pair of shoes has a different shape, depth, and sole hardness. The insoles mold uniquely to your foot in that shoe. Moving them between shoes compromises the custom fit and comfort. For best results, dedicate one pair of insoles to each pair of shoes. Many of our customers order multiple pairs so they can enjoy perfect comfort in every shoe they wear.
Are the insoles washable?
Yes, but only by hand. Use a damp cloth with mild soap to clean
them—do not submerge them in water or put them in the washing machine, as this may affect the molding technology.
Will they make my shoes feel tight?

I was nervous about trying something new since I’d already gone through a couple pairs of generic insoles that didn’t do much. But molding these to my feet was surprisingly easy, and the difference has been night and day. My morning walks to the train used to leave me sore before the day even began, but now I’m comfortable from start to finish. These were absolutely worth it.

I’ve been in construction for 20+ years, and my feet take a beating on concrete floors all day. After molding these insoles to my boots, I could instantly feel how much better the support was compared to store-bought pairs. They don’t just cushion — they actually fit my arches. I can get through a 10-hour shift without limping home. So I decided to buy another pair for my other shoes.

These insoles helped me more than I expected. I’m a nurse and spend long hours on my feet. By the end of a shift, I used to have this deep soreness that made it hard to keep moving. Since switching to these, I can finish a full 12-hour shift and still have the energy to walk my dog after work. Huge improvement in my day-to-day life.

I originally thought all insoles were the same until I tried these. The heat-molding process gave me a fit I’ve never felt before, almost like custom orthotics. I use them in my running shoes, and I’ve noticed my stride feels lighter and more stable. I’m not cutting my runs short anymore.

I bought these because my old insoles kept wearing out after just a couple of months. These feel much sturdier, and after molding them they fit like they were made just for me. I’ve been wearing them for six weeks now and even after long days at work plus errands, my feet feel supported and comfortable. Definitely buying another pair for my sneakers.

I can’t believe the difference these insoles have made. For months, I would wake up dreading those first steps out of bed because the stiffness in my feet was so bad. By the time I got to work and had to stand on hard floors all day, the soreness would build up until I just wanted to sit down. I tried cheaper insoles from the store, but they always felt too generic and wore out quickly.
When I found Koprez, I was skeptical but desperate. The molding process was easy, and once they were shaped to my feet, I immediately felt the difference. The support actually matches my arch instead of forcing it into an unnatural position. Walking feels smoother, and I don’t get that sharp pressure in my heel anymore.
Now I can get through a full shift, run errands afterward, and still have enough energy to cook dinner without rushing to sit down. Even my husband noticed I’m moving around more freely at home. For the first time in a long while, I feel like my feet aren’t holding me back. Honestly, these insoles have been one of the best purchases I’ve made for my health and comfort.

I work long shifts as a nurse, sometimes 12+ hours straight, constantly on my feet. By the time I got home, my feet used to ache so badly that I’d just collapse on the couch. Since switching to the Koprez Insoles, I’ve noticed such a big difference. The custom fit molded to my arch perfectly, and it feels like the insoles are carrying some of the load for me. Even on back-to-back shifts, I don’t feel that sharp soreness in the mornings anymore. Honestly, I wish I had tried these years ago. They’ve completely changed how I get through my day.

As a mom of three, I’m constantly on my feet. Cooking, cleaning, grocery shopping, and chasing after kids. By the end of the day, my feet used to feel so heavy and sore that I just wanted to collapse on the couch. I even thought about skipping family outings sometimes because I didn’t think I could handle all the walking.
I decided to buy 2 pairs of the Koprez CustomFit Insoles after reading about the molding technology, and I’m so glad I did. Once I slipped them into my sneakers, I could immediately tell the difference. The way they supported my arch and heel made every step feel lighter. Even after a full day running errands and playing with the kids, my feet don’t ache the way they used to.
The best part is that I feel more present with my family. I don’t have to say “let’s stop, my feet hurt” anymore. We can spend the whole day out together, and I still have energy left. I’m so glad I bought an extra pair too, so no switching them out each time I switch shoes. These insoles really have made everyday life so much more enjoyable.

Even though I have a desk job, I’m up and down all day, walking between departments and running errands. I didn’t realize how much strain that constant movement was putting on my feet until I tried Koprez Insoles. The fit feels natural, like the support is placed exactly where my feet need it most. By the end of the day, instead of feeling weighed down, I actually have energy to go to the gym or take a walk with my family. It’s the first time I’ve had insoles that truly fit my feet, not just the shoe.

Working retail means I’m on my feet for 15,000 steps or more every shift. Before these insoles, I’d limp home and dread doing it all again the next day. With the Koprez CustomFit Insoles, the pounding I used to feel in my heels and arches is almost completely gone. What I love most is how natural they feel…flexible enough to move with me, but solid where it counts. After a week, I realized I wasn’t thinking about my feet anymore. Back to buy another pair!

After long shifts, I used to come home with aching arches. With these insoles, I can make it through the day without thinking about my feet at all.

I bought these right before a weekend trip where I knew I’d be walking a lot, and they completely changed the experience for me. Normally, I’d be looking for places to sit and rest every hour or so, but with the Koprez Insoles, I stayed comfortable the whole time. The fit was snug and supportive, and the cushioning absorbed all the pressure from the miles of walking we did through the city. I actually enjoyed being on my feet again. Now they’re staying in my shoes permanently. I won’t travel without them.
