sounds to me you are a little modest ;)... but a little modesty is always needed to ad a little push for progression... never being mediocre and satisfied with your current stand...
with that said, I don't think i am any expert on CT fit suggestions and have been debating between a 10 or an 11 since i usually wear 10.5 shoes. Also i am looking at slingshot. I did have the idea recently that i'd go with the 11 (the 10s are just really uncomfortable after even a few min. in the store) and if the bindings proved to be a little large (initially or after breaking in) then i might consider putting some kind of rubber or foam piece in the toe to make it "smaller" and tighter. The added pieces might add shock absorption too...? It would especially work well with bindings with removable liners where the added pieces could stay between the outer shell and the liner. Any one have any opinions to add to this idea?????
