Frequently Asked Questions
Everything you need to know about your next pair of high-performance sneakers.
How do I determine the right shoe size for Flux Footwear?
We recommend measuring your foot from heel to toe and consulting our comprehensive Size Guide. Our athletic shoes generally fit true to size, but we suggest sizing up a half-size if you prefer a wider fit for high-intensity training.
What is your return policy for worn sports gear?
We offer a 30-day trial period on all Flux Footwear. If you aren't satisfied with the performance or fit after a few workouts, you can return them for a full refund or exchange, provided they are not excessively damaged.
How long does shipping take within the United States?
Standard shipping typically takes 3-5 business days. We also offer expedited 2-day shipping for athletes who need their gear ready for an upcoming event or race.
Are Flux Footwear shoes suitable for both road and trail running?
While our core collection is optimized for road running and gym stability, our 'Apex' line features multi-directional lugs specifically designed for superior grip on rugged trail terrain.
Do you offer international shipping?
Yes, we ship to over 50 countries worldwide. International shipping rates and delivery times vary by location and will be calculated at checkout.
How should I clean my Flux performance sneakers?
To preserve the integrity of the technical fabrics, we recommend hand washing with cold water and mild detergent. Avoid machine drying; instead, air dry your shoes away from direct heat sources.
