Baffin Impact Winter Boots - Men'sis rated5.0out of5by1.
Rated5out of5byfromWinter WarmI work outside in the winter under all conditions. I have a job which requires standing out in the weather with limited walking. The Baffin Impact was purchased last winter (2013) for cold conditions starting at the low 20's F and down. I have used them for about a year. They have a very thick inner liner and a separate grid insole under the liner to provide an air insulation gap. When you first put them on they feel tight and under-sized. After walking a few minutes, the insulation conforms and they feel roomy even with thick socks. Last season I used them in -10 F weather and they performed well. I tend to have cold feet and occasionally used a chemical foot warmer. This year I have added an electric foot warmer. It has only been tested down to 11 degrees this year but looks like it will perform well to -20. There is an upper adjustment strap which holds the batteries of the foot warmers securely. One other site listed these boots as waterproof. REI does not. They will take in water if submerged so these are not intended for cold/wet conditions where water goes above the rubber. Like all boots, moisture build up is a problem. With the combination of thick liners and air space below the liners, moisture can build up. The liners are removable but takes a little practice to get them back in. I have since ordered a boot dryer to keep them as dry inside as possible. REI does not offer the extra replacement liners and I had to buy these at another site. A minus here. After a year there is no appreciable wear on the sole and the Impact boots appear to be well built. Because of the weight and bulk they may be a bit much for extended walking and seem well suited for applications when standing on cold pavement or ice. I don't think I will ever get a chance to test the comfort rating of -148 F. I am satisfied if they perform well for several hours at -20. I give them five stars and they fit in well for cold dry conditions at 20 F and below.
