SLIM Low Cushion Support Insole with Arch Flex Technology

I purchased these inserts to replace the stock inserts in my Five Ten Freerider shoes because my toes were going numb when I would cycle. I read an article from a physiotherapist that highly recommended these so I purchased them. I put these in right before an overnight bike trip and rode 55 miles each day. I did not have any foot pain or numbness on the first day and only very minimal numbness the second day so I’d say these did exactly what they were intended to do! I wasn’t sure after doing the wet foot on paper test if my arch was high or medium so I went with medium. I probably could have gone for the high arch and may consider buying a pair to test out and put in other shoes. I did try these in my On running shoes to see how they felt walking around and the metatarsal bump does take getting use to. I also tried to fit these into my Veja sneakers last weekend and they did not fit at all (too big). I wear a women’s 8 (38) and the M 6/W 7.5-8 worked in most of my athletic shoes.

I new to bike cleats and my feet were going numb on longer rides. I researched insoles and these popped up as a favorite for tight fitting shoes like cycling shoes or ice skates. I used them on a 100 mile ride in my New Balance spin shoes and they worked like a charm. My feet started feeling a little tingly but I did not get the full on numbness like before (and that was a 35 mile ride). I am confident these will be perfect when I get my cycle shoes with stiffer soles. I might get a pair for my spin shoes as my feet go numb during class. I just wish the price was a little lower.

When i first stepped into my shoe these felt kinda weird while standing, there is a little dome the supports the palm of your foot. However while riding the dome is not noticeable at all. These provide a good deal of support while riding and feel great. Also MUCH cheaper than custom foot bed i got with a bike fit. i would buy these gain before bothering with the custom insoles again.

I’ve purchased 3 sets of these for cycling shoes and speed skates. They are nice, long lasting, thin and work great. The bump works to move blood and keep your feet fresh during extended use. If you don’t want to spring for a custom heat modeled insoles, these are your best bet.

I purchased the Icebug slim low insole, medium arch, size 11 (U.S.) insoles for my Sidi Genius size 44 1/2 cycling shoes. Size 11 is larger than my Sidi insoles so I used the Sidi insoles as a pattern to trim down the Icebug insoles in the front foot area (not touching any of the arch support area). The front area of the Icebug slim insole is about the same thickness as my original Sidi insole so my shoes still fit me perfectly as they did before but now I have good arch support. It was cool out the first day I wore them. I was wearing a pair of thin socks under heavier wool socks. I couldn't feel the bump at all that some people have discussed. It was a nice warm day the next time I rode my bike. I wore my standard low-cut socks. I barely felt the bump when I put on my cycling shoes and didn't notice the bump at all on my ride. As for the arch support, I took the 'wet foot' test to determine that I needed a medium arch support and medium fits me just right. I'm very happy with my purchase.

After reading an in-depth analysis/comparison of footbeds I decided to try these. They got a 4.9 out of 5 in the analysis so thought they would be quite good. I was disappointed. The ones I received were way too wide in the Arch so that trimming was really difficult and ended up being impossible. I traced my current insoles then trimmed but the size on the IceBug was so large I couldn't bring them down to a normal insole around the arch. I had even ordered one size smaller in the IceBug. In addition from the arch forward the material is only 2mm thick which was what I wanted but it was flexible enough that it kept folding. I was expecting a little more stiffness or density forward of the arch but it was just flimsy. I threw them out after repeated attempts to trim them. They were never worn. So sorry to give negative results. If they were reasonable in width and if the foam forward of the arch had some density/firmness they might work.

The metatarsal bump is incredible. I put these in my Shimano SH-MT700 (size 46) cycling shoes, and my feet were totally pain free after a 2 day 200 mile ride. Prior to these insoles, my feet would start to hurt at around 20-30 miles, and after, they are totally fine! I liked them so much, I bought another pair to put in my hiking boots.

I had purchased these for my cycling shoes since there have been some good reviews online about them. I will say the thin profile fits the cycling shoes nicely and the lining is a nice smooth material. My two issues are the arch support and metatarsal bump. The arch support is pretty flexible which doesnt seem to provide enough support when dealing with the forces of cycling. Second the metatarsal bump is extremely pronounced. While this may be a personal preference, I found this to be very irritating, and feels like there's a large lump under your foot at all times. Ultimately these may be OK for some but I found these two points to be a bit of a deal breaker.
