FAQ

Do I need to remove the original insoles from my shoes?
Yes. Remove the existing shoe insoles and replace them with EASYFEET insoles for the best fit.

How do I choose the right size?
Remove the original insole from your shoe and compare it with the EASYFEET size chart. If your shoes are between sizes, order the larger size and trim only the toe area if needed.

Are EASYFEET insoles standard length and width?
The length is standard across EASYFEET models. Width is standard for most models and varies by size. This model uses the standard EASYFEET width by size.

How long do EASYFEET insoles usually last?
Usually, insoles last around six months to a year, depending on body weight, activity type, frequency of use, and visible wear.

Can I wash these insoles?
Machine washing or soaking is not recommended. Clean the insoles with a damp cloth and mild detergent.

Are these insoles waterproof?
No. This product is not waterproof.

What if the insoles squeak?
Squeaking can happen because of friction between the insole and the shoe. Try another pair of shoes or add a small amount of talcum powder inside the shoe where the orthotic contacts the shoe material.

Abigail 5/5

EASYFEET Flame Boost - Flexible Sport Insoles for Running and Training (Low Arch)

These are nice quality and they certainly keep you feet warm. But you cannot trim them to exact size - they have a bound edge. I tried them myself (even though my feet are 4 sizes bigger). That worked ok - just leaving a gap at the front - but they are so thick that they made my boots too tight on the uppers. So really it is all about the fit.

Ryan B. 5/5

EASYFEET Flame Boost - Flexible Sport Insoles for Running and Training (Low Arch)

ou can sometimes go to pick out the correct inserts. However the packaging made it really easy to know exactly what I needed to do. It had clear-cut instructions and I was able to do it within minutes. They give you guidelines on the bottom of the inserts to trim it down if you needed some of the smaller size. I didn't need to trim it down but I was OK if I needed to because it was pretty easy. I took out my old inserts and slip the new ones in and boom I was done. It didn't take long to feel comfortable wearing them. It's been nice having a supportive arch with nice shoe cushion. Would do again if needed. Very nice!

Lanabird 5/5

EASYFEET Flame Boost - Flexible Sport Insoles for Running and Training (Low Arch)

These insoles are great! They are perfect for running shoes . They have just enough gel cushion pads that provide enough comfort for your sports activities. They reduce stress on your lower body joints. They absorb shock movement and cushion your feet. The insoles provide great arch and lateral support! These help you to be able to stand in your feet for a longer period of time.you only need to trim them down just a touch to fit in your favorite shoes! Overall these are a great pair of insoles to have!!

Margaret K. 4/5

EASYFEET Flame Boost - Flexible Sport Insoles for Running and Training (Low Arch)

My husband is a chef and on his feet ALL day!! He comes home with tired achy feet and no shoes have really helped with the pains. We tried these thinking maybe with all the walking and running and bending he does all day they would provide a little bit of comfort and he loves them! Even after his 10-12 hours shifts he will come home with no more soreness. They did take a little breaking into, the first time he wore them, he had to adjust to get used to them, but after a few hours he could immediately feel the ease.

Martin E. 5/5

EASYFEET Flame Boost - Flexible Sport Insoles for Running and Training (Low Arch)

I have always had a problem with comfort in shoes until I received this product. It is super comfortable and extremely easy to use. It really makes me feel like I am walking on air. After a few days using there is no odor at all which is comforting. I highly suggest these for anyone including those with foot problems.

Andrew L. 5/5

EASYFEET Flame Boost - Flexible Sport Insoles for Running and Training (Low Arch)

I took these insoles out of the box, put them on and wore them the rest of the day! Really comfortable! They are loose as opposed to lace-up sneakers but it's just so nice to be able to slip them on and off. I love them! I would definitely recommend. And I got my usual size too. I wear 8.5 in EasyFeet so I got that size for these and it worked perfect. Very happy!

Ladyjanet 5/5

EASYFEET Flame Boost - Flexible Sport Insoles for Running and Training (Low Arch)

I really like that these inserts s is to add too much extra height or padding yet still offered additional comfort. I felt my arch was well supported and that impact didn't seem as jarring to my heels while running. I definitely felt more stable running around with my daughters morning JROTC physical training workouts.

Jane D. 5/5

EASYFEET Flame Boost - Flexible Sport Insoles for Running and Training (Low Arch)

Oh my goodness my feet are in absolute heaven. I got these to try and they are perfect. I work 9 hour shifts on concrete. So I put these in my shoes and prayed. I love them. My feet love them my legs are not hurting or tired at the end of my shift. I couldn't believe the difference starting the first hour of my shift. I wish I knew about these 5 years ago. Thank you.

Janice H. 4/5

EASYFEET Flame Boost - Flexible Sport Insoles for Running and Training (Low Arch)

My favorite insole to put in my sneakers for daily walking or hiking. I love the foam, it gives me that extra cushion without my feet sliding in my sneaker. I get great support and stability for my arch. After using these for a couple of weeks, my feet were not aching. I felt great support on my knees and back. I would definitely recommend these EasyFeet insoles.

Dairl 5/5

EASYFEET Flame Boost - Flexible Sport Insoles for Running and Training (Low Arch)

I'll start off by saying I have heel spurs and arch issues with my feet. I wanted to use these insoles for about a week to give an honest review. They were easy to cut and fit into my shoes, and very comfy to wear. The day before I used them I was on my feet all day, and I was in a lot of pain. When I wore these insoles, I immediately felt relief, my feet were cushioned and supported. Every day since, I've worn them and I'm very pleased with how well they work! I have already recommended these to my family, and I would recommend them to anyone!
