I have picked (BS800 Red Black) right size (42) shoe with an extra gel sole (standard sole which come with the shoe is not so great), used it for couple if time and now i feel the shoe has expanded a bit and feel very loose and not at all comfortable to use it.
Thanks for taking the time to write to us,
