This week on Dezeen, a man was hospitalised after falling into an art installation by Anish Kapoor, Adidas unveiled a concept trainer that mimics the feeling of running on sand, and the Dezeen Awards shortlists were unveiled.

A visitor to the Serralves museum in Porto, Portugal, was injured after falling into British Artist Anish Kapoor's 1992 piece, Descent into Limbo. The piece features a 2.5-metre hole in the floor, painted black to give the impression of an infinite drop down.

A spokesperson from the museum later told Dezeen that the visitor "has already left the hospital and he is recovering well".

Designer Aarish Netarwala designed a concept shoe for Adidas that imitates the experience of running on sand to increase the fitness of the wearer.

Featuring a lattice sole that replicates the feeling of sinking into sand, the Grit concept shoe makes workouts more effective. Netarwala was inspired to create the design after seeing athletes running up and down a sand dune in California.

Meanwhile, competitor Nike made the news by removing a balaclava from sale, after critics argued that the design enforced racial profiling and glamorised violence

We announced all four shortlists for the inaugural Dezeen Awards, in the architecture, interiors, design and studio categories.

Projects on the shortlist are located in 28 different countries, with highlights including a bamboo sports hall in Thailand, a rammed-earth cricket pavilion in Rwanda and a gallery in a former illegal sex shop in Japan.

In tall building news, a proposed 20-storey-high tower designed by the late Will Alsop for London was revealed to be starting on site soon.

The building will be raised on stilts over an existing five-storey building called Heliport House, and will be clad in irregularly shaped panels of weathering steel.

Also, US architecture firm Studio Gang revealed renderings of a new 40-storey apartment building for San Francisco, which will feature windows spiralling around the tower's exterior.

Foster + Partners' 120-metre-tall tower will still be built in Budapest, it was announced this week, despite the country issuing a ban on all buildings over 90 metres.

Scheduled to be completed in 2021, the building, named MOL Campus, will be 30 metres taller than Budapest's current tallest building.

News of Foster + Partners' Mexico City airport also made headlines this week, after Mexico's next president called a referendum so the public can decide whether to continue construction.

"So we don't make the wrong decision, the best thing is to ask," said the incoming president López Obrador.

Popular projects this week include John Pawson's transformation of an ornate convent and hospital into a hotel in Tel Aviv, Monoarchi's tree-house-inspired house on stilts in a remote Chinese village and a shingled house on Martha's Vineyard – an island off the coast of Massachusetts.
