Crocs India — not to find a perfect fit

Address:

Udupi, Karnataka, 576 104

I recently bought a new crocs and i'm not able to get a great fit... Like the size 9 is too tight while the size 10 is too loose... So i wanted to know whether you guys allow an exchange and help me get a great size... Bdw i exchanged the product once for colour issues... So i also wanted to know whether i could change the product again so that i could get the perfect fit...
