Replying to 08/09 Salomon SPK Kaos Boots

Im not if breaking boots in makes a big difference, but it was my first day riding today with 08/09 spk kaos boots and it was fucking hell by the end of it. the boots boast that they are the most comfortable with alot of padding for landings and what not, but my feet were killing me after 2 hours. does breaking in boots make a difference after you ride them for abit, and usually how long? has anyone else had this problem with these boots? i feel like i got to small of a pair?

my feet are a fucking fire man, helppp please
