M-Pact Sockliner is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from A must-have for all boots and shoesI have to agree completely with "Decca". These foot-beds have transformed my new Magnum Vipers into boots almost as comfortable as my old and new Magnum Stealth boots. When I felt the immediate comfort, I went right ahead and bought a new pair of Magnum Stealth boots. When they arrived, I was not really surprised to see that they also had these same "Impact" foot-beds in them. It looks to me as if Magnum continues to understand arch support better than just about anyone else. I have a history of plantar fasciitis, which only Magnum boots have been able to help me with.

Rated 5 out of 5 by from HOW TO MAKE GOOD BOOTS GREATThese are an absolute must have. They give your feet the added comfort needed after long stints of wear. I found they help relieve the numbness from your feet when standing in one place or constantly moving. But more importantly they ease the shock from jumping and landing. They may only seem small but they make a big difference. Just remember to change them regularly for the best effect I work on a 3 month cycle.

Rated 5 out of 5 by from comfortHave worn the 6 in boot for years. I'm on my feet every day so I bought 2 pairs and switched every day to allow the cushion in the soles to return. After 6 months the boot was still in great condition so I would buy the new insoles to extend the life of the shoe.

Which boot took the place of Magnum Women's Stealth Force 6.0 SZ WPi 5116?

Asked by: ahogue
We have an 8 inch Stealth Force (5114) boot that is available with those options. You might also consider trying a men's Stealth Force boot, which is available in a waterproof 6 inch (5473). You just need to order 1.5 sizes down. If you're a size 7 you would order a men's size 5.5. I hope this helps!

why do you make boots size 16 but don't offer replacement insoles in that size?

Asked by: rebelaa
These insoles are offered in some but not all of the Magnum boots. The boots that are available in size 16, unfortunately do not come stock with the M-PACT insole, which is why they are not available in size 16.

Do you carry wide sock liners

Asked by: Darrell
The sock liners are constructed so as to be wide enough to fit into wide shoes nicely, therefore we carry only one size.

Are the U.S. yellow sock liners the same as the all grey available in the UK. 

Asked by: brianuk
No, the grey UK sockliners are the MPACT sockliners. We also offer these in a number of styles and sell them separate as well.
