FREQUENTLY ASKED QUESTIONS
What size should I choose? Do LUXIAOJUN shoes run true to size?
Most customers find the shoes fit true to size, with several reviewers stating they match their usual shoe size perfectly. However, the shoes have a "slim, low volume fit". For the most accurate fit, we recommend measuring your foot (from heel to longest toe) and matching it to our specific size chart, which is available on every product page.
What makes LUXIAOJUN shoes different from regular trainers?
Weightlifting shoes like LUXIAOJUN provide a rigid, stable platform and a raised heel to support proper positioning in squats and Olympic lifts. Regular trainers prioritize cushioning and flexibility, which can reduce stability and power transfer when lifting heavy loads. They are specifically engineered to maximize "stability" and "support" for the user.
Why are they so popular among professional athletes?
LUXIAOJUN shoes are designed and tested by Olympic Gold Medalist Lu Xiaojun, a three-time Olympic gold medalist. They underwent over two years of research and development before being officially launched, ensuring they meet the highest standards of competition. They are battle-tested at the highest levels of the sport, with athletes like Karlos Nasar using them to shatter world records.
