Robert Kardashian and his sister Khloe are focused on their fitness goals. Not only are the siblings hitting the gym regularly to get back in shape, they are also doing it in style and helping others at the same time. The pair has expressed support to a project by Athletic Propulsion Labs, or APL, to raise funds toward Breast Cancer awareness and research.

Khloe took a moment to get a shot of the workout shoes that she's wearing during one of her gym sessions. She was sporting a pair of pink sneakers and she expressed her support to the cause with the photo caption: "I'm honored to be rocking these @aplrunning sneakers in an effort to help fight the fight against breast cancer. With every pair sold a percentage goes to help in this fight! If YOU want to participate in the battle go to APLrunning.com and grab your baby pink, breast cancer fighting sneakers! Thank you @adamgoldston and @ryangoldston for all of your efforts in winning this war!"

Her brother Rob, who has also been regulary working out with the same trainer as Khloe, also supports the project. Although Rob is a lot more private about his workout sessions and doesn't post gym selfies, he expressed his support to the APL project by promoting it via Twitter.

The sneakers are called the "TechLoom Pro Breast Cancer Awareness Shoes." The shoes are available in both men and women's versions and come in pink, the traditional colour used to promote Breast Cancer awareness.

According to the APL website, 10% of the gross sales of both the men's and women's Techloom Pro BCA shoes as well as the Vision Low Men's Basketball Shoe will go to the Women's Cancer Research Fund. Donations will be taken from sales made within October 2014 until December 2014.

The product is now sold out for sizes 7 and 13 for the men's version and also sold out in all sizes except 11.5 for women. However, women can still purchase the shoe if they order the men's version and just order 1.5 sizes smaller.

Khloe and Rob have been getting their heads down in the past several weeks and are on their way to their fitness goals, according to their personal trainer, Gunnar Peterson. The celebrity fitness coach has been working with the siblings and has given positive reviews on their work ethic and the progress that they are making. Rob has been struggling with his weight in the past year and his sister Khloe, with the support of the rest of the family, has been making an effort to help him get back on track both with fitness and with his depression as documented in the reality show "Keeping Up With the Kardashians."
