USD Carbon sizing for wide feet

I want to buy the USD Carbon 2021 but I am not sure about the sizing. My foot length is 275 mm and my foot width is 108 mm. Until now I've been skating the SL Henderson in size 42,5 but they are pretty wide so they fitted me well. What size of USD Carbon should I choose? 

USD Carbon size 43 has a length of 275 mm but I don't know about the width. Will I be able to heat mold them to a comfortable width? The other option is size 44 that is 282 mm long so I guess they would be a bit wider but maybe a tad too long.

Are there any carbon users who could help me out? Thanks
