The 68-page Tred will appear in JD stores from November 21 with a one million print run, and will be promoted as a poly-bagged supplement to the December issues of Maxim, B and Touch.
Tred will be given free to customers who purchase goods over a specified value, likely to be £40, and will be sold to other customers with a cover price of £1.50. It will add value with discount vouchers, including £50 off Club 18-30 holidays, £3 off videos and DVDs from Blackstar.co.uk and CDs priced £7.99.
The magazine, aimed at 16- to 23-year-old men and women, will carry a mix of features on urban style and sports fashion, music and celebrities, along with vox pops of JD Sports customers and staff.
Tred is edited by David Roberts, who has previously worked on GQ and Nova. Its design aims to give the magazine an edgy tone and the first issue's cover features Megaman from So Solid Crew. The editorial ratio will be much higher than that of most retail customer titles.
The first issue will be researched to ascertain customer feedback, and the plan is to roll out the magazine with a quarterly frequency next year.
JD Sports marketing director Andy Helme said the title was key to kicking off the chain's Christmas marketing activity, and it will be followed with window display promotion and outdoor and radio advertising in December.
According to Helme, the magazine's overriding objective is to build the brand with what research suggests are the chain's core customers, 19-year-old men and women.
He added that Tred has been designed to specifically appeal to this group.
