An inflatable packer includes a reinforcing element constructed from first and second layers of alternately biased calendered steel cables. Fixed and sliding end shoes each are a single machined structure and include a roughened inner cylindrical surface disposed about an end of the reinforcing element. Upper and lower hardened rings, formed from a liquid adhesive, have the ends of the reinforcing element embedded therein and are bonded to the end shoes.
