Hallo everyone,i want to buy omer stingray fins , could you give me some advice about size of footpocket. My size is 42/43 when i buy a shoes. I use 2 mm sock in summer and 4 mm in winter. I´m a little bit affraid to buy size 41-42 because my former fins were garas 2000 in size 42-43 and they were tight in my 2 mm sock.My foot has distance between heel and toe (longest distance) 26 cm. Thank you , and I applogize for my English. Bye Martin
