Competition: Dezeen has teamed up with London design studio PostlerFerguson to offer readers the chance to win four Staeckler trainer display and storage systems (+ slideshow).

Congratulations to the winners! Robert Chapman from the UK, Casey Chin from the USA, Dominik Zach from Germany, Eric Truong from Canada and Ievi Dethier from Belgium.

The clips in the Staeckler system attach onto a wall and feature a hooked end for hanging shoes at a gentle angle.

The product is designed specifically for trainers, and can used to display collections or as a space-efficient storage solution.

The plastic clips – which are available in either white, grey, blue or orange – hold the shoes securely until released with a simple lift and twist and can be arranged in a variety of layouts.

"A small footprint means they can be installed to suit any situation, whether a wall-sized grid to showcase a collection or a single pair slotted into the leftover space of a small apartment," said PostlerFerguson co-founder Martin Postler.

London- and Hamburg-based designers Ian Ferguson and Martin Postler have set up a separate company underneath the umbrella of their studio PostlerFerguson to produce and sell the Staeckler.

Five Dezeen readers will each receive a set of four clips, in a selection of the available colours. The products are also available to purchase from the Staeckler website.

Other products by the studio include an air purifier that breaks down pollen and dust at a molecular level and fish packaging that promotes less endangered species.

This competition is now closed. Five winners will be selected at random and notified by email, and their names will be published at the top of this page. Dezeen competitions are international and entries are accepted from readers in any country.
