A substrate having discrete copper laminae for positioning proximate an odour causing area of a user's body. The lamina are spaced apart to provide channels between adjacent laminae and the substrate. The high density of the laminae and channels cooperate to control odour. Several embodiments are disclosed for use in a variety of clothing and footwear articles.

An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

Methods for fracturing a subterranean formation penetrated by a well bore are provided, the method comprising the step of injecting a well treatment fluid into the well bore at a pressure and flow rate sufficient to fracture the subterranean formation, wherein the well treatment fluid comprises one or more iron-containing compounds and one or more booster compounds. The methods can be used to reduce viscosity and to facilitate the decomposition of acrylamide-containing polymers.

A pair of shoes and shoe insert covers thereof are provided. The shoe insert cover and a shoe insert are disposed in the pair of shoes. The shoe insert cover has a shoe insert cover top and at least one shoe insert cover bottom, and the shoe insert cover top is connected to the at least one shoe insert cover bottom. The shoe insert is located between the shoe insert cover top and the shoe insert cover bottom, and the shoe insert cover bottom is located between the shoe insert and a sole portion of the shoe. A user with sweating feet can easily replace a surface material of the shoe.
