American singer and actress Selena Gomez has collaborated with PUMA to design the Phenom Lux shoe, available to buy from April 6.

Proceeds from sales will go towards the Lupus Research Alliance - the world's leading private funder of Lupus research - and Gomez, who was announced as the brand's ambassador in September last year, commented 'It's been really fun to work so closely with PUMA on the design of this shoe. I’m also proud to partner with them in helping to affect lives and bring attention to a cause that is very important to me personally'.
