Each week on NFL fields across America, players often put on custom cleats meticulously designed and a spectacle to view.

But in Week 15 for the Las Vegas Raiders, the vibrant colors and personality on many players feet comes with a story deeper than what reaches the eye.

NFL's "My Cause, My Cleats" campaign is league-wide initiative highlighting passions and charitable causes of NFL players and allowing them to spread awareness for them. This comes in the form of players wearing customized cleats in honor of the causes they have chosen to support.

This season, the Las Vegas Raiders upped the ante for this annual initiative, with the creative team designing customized boxes for each of the 37 players who participated. Each 3D display box contained the cleats as well as an elaborate collage of pictures on the inside lid of that player and their involvement in the charity.

Read through for the stories of four Raiders and what it means to them to get to spotlight these organizations.

ANDRE JAMES, AMERICAN CANCER SOCIETY

In 2017, Andre James watched his father fight through stage four testicular cancer. His father, Marcus, was the first to introduce football to the offensive lineman and didn't miss a single game of Andre's until he became ill. Marcus passed away in 2018, five days before Andre started his 27th straight game as a UCLA Bruin.

One of the groups that provided help to James and his family during that time was the American Cancer Society, which he has chosen as his cause since entering the league in 2019.

"There's a lot of different type of originations and something that's cool is every player chooses an organization that's close to them," Andre James said. "It's a great way to bring awareness to causes."

The American Cancer Society's mission is "to improve the lives of people with cancer and their families through advocacy, research, and patient support, to ensure everyone has an opportunity to prevent, detect, treat, and survive cancer." Something that was invaluable to James' family.

"They're one of the biggest when it comes to cancer research," James said. "All of their funding goes to cancer research and an awesome program."

As James opened his custom box, he was impressed with the custom cleats design – the American Cancer Society's logo painted red over the stars and stripes of the American flag serving as the base.

However, he spent more time admiring the photos attached in the box. Many of them were family photos with his father and himself a baby, Marcus as his Pop Warner coach and the two of them when Andre attended UCLA.

He spent a few seconds in silence looking at the photos, reflecting on his father's life and remembering his why.

"It was one of the hardest things that me and my family had ever been through," he said. "But with the support of all different types of programs that supported us at the time, it was easy to select such a great organization and all the benefits they have."

DYLAN LAUBE, WOUNDED WARRIORS PROJECT

Dylan Laube doesn't take military members and their sacrifices for granted.

The rookie running back has a multitude of ties to the Armed Forces as both of his grandfathers served in the Army, an uncle that served in the Air Force and two close friends who currently serve in the Navy and the Air Force.

With the amount of people in the military from his inner circle, resources for veterans is a cause that strikes a deep chord within him. This prompted him to choose Wounded Warriors Project.

Founded in 2003, Wounded Warriors provides services for wounded and disabled veterans returning home from deployment. Their direct programs include career counseling, and long-term rehabilitative care for soldiers and their families.

"I feel like the military is very underappreciated and to me, it's a personal thing," Laube said. "I feel that the backbone of this country is our military and at the end of the day, I want to give back to them because without them, I wouldn't be able to play this game today."

Laube's cleats are painted in olive green camouflage with the Wounded Warriors Foundation logo featured on the side in black.

There's a sense of joy that comes from not only representing the organization dear to him, but also being able to use his newly-found platform in the NFL.

"I'm seeing all these causes for every single cleat and it's super cool," he said. "It's exciting to see all these players giving back to My Cause My Cleats. It's going to really cool seeing all these cleats come alive on Sundays these next couple of weeks."

ROBERT SPILLANE, OLIVE CREST FOUNDATION

One of the first things Robert Spillane did after signing with the Las Vegas Raiders was look for an organization in his new community in which he could help make an impact.

The linebacker has been open about how he finds strength in his family, who have supported him through the process of navigating the league as an undrafted free agent. At the suggestion of one his close friends from high school, he searched for a cause that helps builds up families and provide caring homes for the youth of Las Vegas.

He landed on Olive Crest Foundation, a nonprofit in Southern Nevada that works alongside the Ronald McDonald House that aims to provide resources to end child abuse and child neglect. They also have several programs to help support foster children from a monetary and emotional standpoint.

"People that go through neglect and abuse deserve love," Spillane said."I'm just glad to be able to partner with them because they do so many things around Vegas supporting those kids."

His cleats are simple, painted dark olive color all around with the airbrushed logo of the foundation starkly standing out for awareness.

The box details included pictures of him spending time with the many children the foundation serves, including photos of Spillane and his wife Shelby hosting a Christmas party for 75 underprivileged and foster children.

ALEXANDER MATTISON, I AM GIFTED FOUNDATION

It's ok to not be ok.

These words were uttered by Alexander Mattison as he emotionally glancing at the cleats he personally designed and words he also has painted on the cleats.

The cleats and his cause are symbolic of him finding a way to see light out the end of his dark tunnel that almost made him quit football.

After being drafted by the Minnesota Vikings in 2019, Mattison started his I AM Gifted Foundation, specializing in supporting mental health awareness and suicide prevention.

Through the efforts of his foundation in hosting youth football camps and donating to scholarship programs across Southern California, Boise, Idaho and Las Vegas, Nevada – he's won multiple NFLPA Community MVP Awards for his advocacy.

"I started my foundation through the inspiration of my own mental health journey, my own mental health struggles, my own mental health adversity," he said. "There was a time where I almost walked away from the game of football and I'm glad I didn't because now, I'm in position to use my platform for good and to help those in a dark time.

"I know when I was in a dark time, all it took was a little bit of light to get me to the end of the tunnel. So, I just hope to be that little bit of light and happiness in anyone's dark time and continue to try and make an impact that way."

The cleats Mattison designed are some of the more extravagant ones on the roster, featuring a two-tone gradient effect of royal purple at the heel into sky blue at the toebox.

On the left cleat underneath the "It's ok to not be ok" inscription is the 988 Suicide and Crisis Lifeline number. He also has the suicide prevention ribbon painted on the outer heel of the left cleat.

On the inner heel of the right cleat is the phrase "your life matters," while the outer heel features a portrait of butterflies flying out of unopened boxes with the phrase "unlock your gift within" on the toebox.

"Some people just don't feel like they matter, but deep down within, every life matters," Mattison said. 'And we just have to make sure we show that support to everyone and you just have to unlock your gift within.

"Unlock that gift, open that box, let those beautiful butterflies spread into the world. Spread that love and positivity."
