Madrid / Spain | Active: 2023-present | Known for: European Cup rail wins, Spanish slopestyle titles, X Games Aspen Knuckle Huck, SuperUnknown 22 | Current: RFEDI 2025/26 freeski athlete
The Big Air knuckle in Aspen disappeared into grey January light, snow falling slowly over a course built for improvisation rather than safe repetition. Maria Esteban Uña dropped into the X Games Women’s Ski Knuckle Huck with a field that included Marin Hamill, Alaïs Develay, Anni Kärävä, Jennie Lee Burmansson, Grace Elden and Finley Good.
For a Spanish skier still building her senior profile, the moment carried real weight. Esteban was not arriving with an Olympic medal or a decade of X Games history. She arrived through rails, European Cup results, national slopestyle titles and video-contest visibility. Downdays described her at Aspen as the “Madrid metal sliding master,” a phrase that captured the route that brought her there.
FIS lists Maria Esteban Uña as a Spanish freestyle skier, born on November 8, 2005, with FIS Code 2539520. Her listed club is Forward Freestyle Academy, while Spanish federation results identify her under FORW-FMDI. That institutional trail matters because it places her inside Spain’s developing freestyle structure rather than only in social-media clips.
Her public FIS record covers freeski slopestyle, big air and rail event starts from 2023 onward. The range is important. Slopestyle asks for a complete run, big air tests one major trick under pressure, and rail events isolate balance, creativity and metal control. Esteban’s best public results so far have come on rails, but her national titles show she is not a one-format skier.
The 2023 Spanish Slopestyle Championships at Baqueira Beret gave Esteban one of her first strong national markers. RFEDI reported that Maialen Oiartzabal won the absolute women’s freeski slopestyle title, with María Esteban in second and Maria Lukas in third. That result placed Esteban on the Spanish senior podium while she was still a teenager.
Baqueira is a useful place to read that stage of her development. The Pyrenean resort gives young freestyle athletes a competition venue with changing mountain weather, shaped park features and a national field that includes riders from different Spanish regional programs. For Esteban, that 2023 silver created the step before her two later national slopestyle wins.
In April 2024, Esteban won the Spanish FIS Slopestyle Championship at Sierra Nevada. RFEDI described the event at Snowpark Sulayr as a spring competition with bright sun and high-quality snow, a setting that gave the riders a clean late-season platform. Esteban took the women’s freeski title ahead of Irene Conde and Alejandra Gracia.
The location gives the result extra context. Sierra Nevada has deep Spanish freestyle history, including the 2017 FIS Freestyle Ski and Snowboard World Championships. Winning there did not make Esteban a global medal contender, but it confirmed her position in Spain’s women’s freeski field. It also gave her a national title before her rail-event breakthrough in Europe.
The 2024/25 season changed the way Esteban’s profile reads. FIS lists her winning the European Cup freeski rail event in Den Haag on December 6, 2024, then winning another European Cup rail event in Szczyrk, Poland, on March 8, 2025. Those two wins gave her the strongest results of her public record.
Rail events reward a different skill set from classic slopestyle. The skier has less time to hide mistakes, and judging focuses on difficulty, execution, style, variety and how naturally each feature is used. Esteban’s back-to-back European Cup wins point toward a rider with strong pressure control, fast decision-making and enough creativity to stand out in a rail-specific field.
Esteban followed the rail-event season with another Spanish slopestyle title in 2025. RFEDI reported that she won the women’s category at Baqueira Beret with 20.00 points, ahead of Alejandra Gracia and Irene Conde. The scoreline was modest, but the result added continuity: 2023 podium, 2024 title, 2025 title.
RFEDI later included María Esteban, born in 2005 and representing FORW-FMDI, in its 2025/26 national team publication under freeski. That selection gives her current trajectory a formal frame. She is not only a rail-event clip skier; she is part of the Spanish federation’s Olympic-cycle talent structure, alongside other young athletes being developed through national and regional support.
In 2025, Esteban’s name also appeared among the finalists for Level 1’s SuperUnknown 22. Freeride.cz listed her in the finalist group connected to Palisades Tahoe, alongside riders such as Elsa Sjoestedt, Rylie Warnick, Anouck Brodard, Maé Biedermann, Marea Adams and others. That placed her in a global video-discovery format, not just a federation pathway.
SuperUnknown matters for a skier like Esteban because it rewards clips, trick selection and style in a way that traditional rankings cannot. A rider has to make an edit convincing enough to travel beyond her home scene. For Esteban, that finalist listing fits the same pattern as her rail wins: visibility built through metal features, compact tricks and footage that reads well outside Spain.
The safest technical frame is rail-first, with slopestyle and knuckle huck range developing around it. Her public results point to comfort on metal: rail events in Den Haag, Szczyrk and Innsbruck, plus X Games attention for a rodeo 540 over the knuckle. The building blocks are approach speed, flat-base control, pressure through the feet, stable takeoffs and exits that stay organized.
Her slopestyle results add a second layer. A full course forces her to connect rails, jumps and landings without losing rhythm. That means she needs more than one strong feature. She has to manage speed across the whole line, land clean enough to reach the next hit, and keep tricks readable under judging pressure. That combination is still developing, but the structure is already visible.
X Games Aspen 2026 gave Esteban her largest public stage so far. Freeskier listed her among the invited Women’s Ski Knuckle Huck athletes, while Prime Skiing’s result recap placed her fourth behind Marin Hamill, Alaïs Develay and Anni Kärävä. Downdays highlighted her rodeo 540 as one of the session’s memorable non-podium moments.
That result does not make her an X Games medalist, but it changes the ceiling of her profile. Esteban now has verified national titles, European Cup rail wins, an Innsbruck European Cup rail podium, SuperUnknown finalist visibility and an X Games fourth place. The next measurable step is consistency across bigger invitational events, stronger slopestyle scores and more results that prove her rail-event strength can carry into full-course competition.
