Sometime early in January of 1979, we will send you the name and address of your nearest PONY dealer where you can try on a pair of Pony Express VSD or Lady Express VSD running shoes. Naturally, you're under no obligation to buy but by sending in this coupon, it will guarantee that the PONY dealer you visit has the VSD model you want in your size! Do it now. You'll be a step ahead tomorrow.
(A) The upper is lightweight cushioned nylon reinforced with suede at points of stress and with arch bandages for lateral support. The upper has a unique mesh panel for true breathability preventing heat buildup and minimizing the resultant perspiration and fatigue.
(B) The sole is slightly wider across the heel, the shock absorption studs are more numerous, wider and arranged closer together to provide greater stability and increase resistance to wear. The sole is also wider across the ball and the shock absorption studs arranged along the outside of the ball of the foot are reinforced at the base for increased stability and durability. A new molding process allows the inside ball area to be reinforced with a special rubber compound for improved traction and resistance to abrasion.
(C) Our new seamless nylon upper is made on a moccasin construction which reduces weight, allows the toes to spread without construction and maximizes forefoot flexibility.
