Police have not been able to identify where the foot came from but say forensic tests reveal it is likely to have come from a man, white, older than 17 and between 164 and 178 cm tall.
The foot was found in a size nine and a half Vision-brand trainer and a dark grey sock. The trainer was grey and blue with a white rubber sole and a blue V logo on the side.
Police in Gloucestershire are renewing their appeal for information after a human foot was found by a riverbank. The decomposed foot was found by a couple walking along the River Severn in Deerhurst on Saturday March 21 2009.
Since the discovery police have been trying to identify the person the body part came from and how it came to be on the riverbank.
