Thin, lightweight footwear made of a polyethylene material that is composed of a top part and a sole part that are sewn together such that when fitted properly to the wearer’s foot the footwear encompasses the foot and extends to the level of the ankle. A disclosed decoding method and decoder include a radial incoherence detector that increases the probability of detecting RI and improves the decoding performance in terms of the bit error rate of the decoded signal. The audio content reference and a telephone number of an audio server form the link on the page, so that when a user selects that link, the wireless device establishes a voice connection to the audio server using the telephone number and then provides the audio server with the audio content reference so that the user hears the specifically referenced audio content over the voice channel. The processing device determines if the retrieved data is compressed.
