Hey Rachel,
Thanks for taking the time to leave your feedback on the Form Soft Touch Hi-Rise Compression 3/4 Tights, and for giving us 4 stars!
We're glad to hear they're generally quite comfortable - that's great that the overall feel is working well for you!
Your detailed feedback about needing a broader calf opening or stretchier construction to accommodate wider calf muscles is really valuable and something we'll pass along to our product team for future considerations.
Thanks for choosing 2XU!
Warm regards,
Cem
