an update:
yesterday i travelled 3 hours to Sheffield, ( i had to attend a university visit there so i could combine the two things!) and went to Puckstop the rink shop there as i had ordered a pair of jackson freestyle boots in what i hoped would be my size.
i tried them on and my immediate reaction was 'they are too small' so i tried some other boots on in the next size up and my heel was lifting so i was like 'these are too big!' so i asked to try the Freestyles on again. i then realised that the length was fine but they were not wide enough.
the man who was fitting the boots for me looked at the shape of my foot and said it is really square so its going to be hard to find boots to fit but we will do our best.
eventually after comparing the shape of risport, jackson, graf and edea insoles to the shape of my foot, we concluded that the jacksons were the best shape, but they still werent wide enough. so the guy phoned up the Jackson dealer who said to heat mold them to see if that would help, and that these particular boots stretch a lot as you break them in.
we heat molded them 3 times and finally they were starting to feel more comfortable. i could feel a lot of pressure around my little toe and the toe next to it, but it wasnt pain, just pressure. so we decided to buy them and i would skate in them like that for a few weeks, and if necessary i could get them heat molded again or even punched out.
i wore them for 4 hours last night, just sitting in the house, and by the end my little toes were hurting and they were red, but i didnt have pins and needles or numbness or anything like that.
i skated in them today, and instead of skating tights i wore really thin nylon popsocks and trousers to give my feet a bit more room. i skated for 1 hour with no pain, just pressure. my little toes were red when i took them off but they soon went back to normal.
hopefully all this means that as i break them in the pressure will get slightly less, and they should be really comfortable.
Problems that my new jackson boots have solved:
1) the inablilty to straighten my leg when doing spirals
2) my foot moving around in the boot
3) my heel lifting inside the boot
thanks for your advice everyone!
