I am a construction worker in the midwest this is my favorite and most comfortable boot. It's also the most popular boot amongst all trades, men & women on the jobsite. Can u Please make this model with an insulated 400 gram. It is definitely neccessary in the fall and early winters. 400 Gram Insulation, slip/oil resistant bottom, SAFETY TOE, 8inch & 6inch options. It's already a costly boot, but we the people are willing to pay the price for more options with this particular style of boot. Thanks in advance Best Regards, Mr. Beckham
