Questions
Before you lace up.
Sizing, switching and the fine print.
How does the Adapt Graphene XT fit?
It runs small for most, so size up by ½ for the best fit. Sizes run from men's M5 to M14 and women's W6.5 to W15.5.
Not sure? Exchanges are free, so you can swap sizes at no cost.
I've worn cushioned shoes for years. How do I switch?
Build up gradually. Don't go from injured to 100%. Build your way back.
Start by wearing them for shorter sessions and let your feet adapt before you add longer or heavier training. If you're managing pain or an injury, talk to a qualified clinician about how to progress.
Can I use my HSA or FSA?
Yes. Flux is HSA/FSA eligible through Truemed, which Flux says saves shoppers an average of 30%. Choose Truemed at checkout to see if you qualify.
Shipping, returns and warranty
Shipping is free on domestic orders of $80+. Returns and exchanges are free too (clearance items, apparel and accessories excluded).
The Adapt Guarantee: “If you believe there is a manufacturing defect within 1 year of your original purchase, we'll replace the product free of charge.”
