Black Bamboo Crew Compression Socks

Not sure

Hello, I ordered 4 pairs of black crew compression Regular/M after measuring my calf & was in range for a Regular/M fit. However i have worn 1 Pair for 2 days (not consecutive) & both days found them quite tight around my calf area, when i took the socks off i had quite deep indents on both legs. I realise that you have a 99 day fit guarantee & was wondering how i go about changing the 3 remaining pairs to the wider fitting. If you could let me know I would be very appreciative. Many thanks Kind regards Brian.

Good quality, like them more than the knee high socks. Comfortable on feet. Usally wear them theoughout the day 👍 would recommend.
