It's okay, you can unclench your torso - we're not about to guilt trip you with another of those "5 moves for your abs" January pieces. Nike's latest trainer release is inspired by the core-shredding Medicine Ball in name and structure only.
Two classic models from Nike's extensive catalogue have undergone an aesthetic overhaul for the new Medicine Ball pack - a release that favours luxury and comfort over sweat and cramps.
Calling on the rugged, multi-panelled aesthetic of the weighted gym ball, the Nike Air Trainer Huarache sports a blue leather upper, while its exposed neoprene sock has been reworked in contrasting tan. Greys pick out the remaining details, including the iconic velcro strip.
The pack also sees the return of the Nike Air Trainer 3, inverting the blue and tan of the Huarache across its traditional leather upper and foot strap.
Granted, we're not sure how either shoe embodies the Medicine Balls of old, but when they look this polished who are we to argue? Set for a launch on Hanon on 15 January, you pick up either of the Medicine Ball pack for £97.
