The On Running Slipi On Gradiant Effect Train is a low-top running trainer built around an engineered mesh upper that shifts from a dense black speckled knit at the heel and tongue through to a lighter, more open white mesh at the toe, creating a striking gradient effect. The fine dotted texture across the upper gives it a technical, sporty look that suits everyday training as much as casual wear.Round black laces run diagonally up the instep through a mix of fabric loops and metal-rimmed eyelets, allowing for a secure, adjustable fit, while the padded ankle collar adds comfort around the foot. A red tab at the base of the tongue and a Swiss cross emblem with 'SWISS ENGINEERING' text on the medial side highlight On Running's Swiss design credentials, with subtle branding on the lateral side and heel tab completing the look.Underfoot, this trainer features a thick, moulded white midsole with a distinctive perforated, wave-like cut-out structure that flexes through the arch, offering both cushioning and a lightweight feel. The black rubber outsole uses a diamond and rectangular tread pattern with white accent strips across the forefoot and heel, giving reliable grip where it matters most.With its round toe, low heel height and lace-up closure, this women's trainer is a practical pick for runs, gym sessions or simply adding a technical edge to everyday outfits. The white and black colourway with grey undertones makes it easy to pair with both sportswear and casual denim.
