Over the last few months I’ve had the opportunity to use the 3M™ Thinsulate™ Thermal Insoles in my hiking and work boots. Maine winters can be cold and snowy, cold and slushy or just plain cold. One thing for sure – they are always long. By the middle of May though the snow was gone and the mud here.
Product Description from Thinsulate:
Thinsulate thermal insoles are made up of four layers:
- The top layer is an abrasion resistant fabric, improving durability and containing antimicrobial technology to reduce odor.
- The second is foot-conforming foam – to provide additional comfort.
- A third layer made of Thinsulate insulation bonds the comfort layer and bottom layer, providing exceptional warmth.
- Patented foam in the bottom layer absorbs shock, provides energy return, wicks moisture and includes additional antimicrobial technology to inhibit odor-causing bacteria.
As far as the Thinsulate Thermal Insoles were concerned, it didn’t matter what the temperatures were. I noticed a big difference when I wore them though. My feet stayed warm and dry. I wasn’t so concerned about water leaking into my boots, because I buy waterproof boots and then waterproof them again. My feet perspire a lot (yeah, gross). That leads to them then getting cold. With these insole, my feet don’t perspire as much, so they don’t get chilled either. I don’t notice any smells after I take off my boots, and even better, neither does anyone else.
I wear my hikers when I am out hiking or just outside. My work boots I wear when welding or doing mechanical work. They get plenty of wear and sometimes I wear my work boots every day for 14 hours or so, and then again the next day. I try to remember to take the insoles out and air out the boots, making sure they are dry each morning. When I go hiking, I usually have to cross a stream or two, or try to get around a large puddle or two. On one hike, I stepped into what I thought was a shallow puddle and was surprised when I felt the water rush in the top of my boot. It was cold and I was glad I was close to my starting point. When I got in the car I emptied out my boot and took off my wet socks. At home I took out the insole and hung it up to dry. I didn’t think it would dry out too quickly, and wasn’t sure it would be any good after it got soaked. By morning it was dry and continued to work fine. After 2 months of use, the insoles show some wear around the areas where the balls of my feet hit and the outer edge of the heel area. It hasn’t caused any problems yet, and even though the weather has warmed up, I will continue to use the Thermal Insoles to keep my feet dry. I’ve come to like the cushioned feeling, and lack of odor.
