Generally you should go up a size for Soaps, although I can't say if that applies to the Heely styles

The easiest thing you could do if you can't find a retailer that stocks Soaps is to send HSL an e-mail and ask them, they'll know for sure

Since this is the size/fitting post, i was wondering, in the plate sizing, As the size goes up, does the plate have to get wider or longer? I was wondering this becuase i thought for example, if sumone is a size 5 in SOap shoes, wont the plate be too small to take on most rails? So i thought that maybe ALL the plates were the same size in length.

Yes there's a difference. As a comparison, the plate specification differences between a size 5-6 and a size 13-14 are as follows: From the center line, 5/8 inches wider, 1 inch longer. Using the Slo-Bro as an example, yes the 13-14 lock-in area is wider and not as tight as the 5-6 (a little looser, less lock-in), as the entire plate has merely been expanded (enlarged) in all aspects except the screw channel width and screw hole diameter. There are no additional design elements -ridges/grooves- in a larger plate. You just have more area to cover, hence the reason you must have sized plates to fit the shoes size. Clear as mud, no?

First of all, glad you still have power in your part of Queens. Bet ConEd is pulling out their hair! The only sets I have left in size 9-10 are 2 UHF and one BBK (all in black). Closest I have in Curb-busters is one black and one gray in 7-8, and also one slightly scratched up set of blacks in 7-8. I just swapped them to a a size 10 Ordnance Flint and they fit-on but it is to the absolute front end of the screw channel ears, somewhat short. If you can find a 9-10 set somewhere, it really needs the extra 1/8 inch width and 3/16 length to fit properly. Otherwise, using the smaller size plate the two front screw channel ears will be taking most of the stress. They will probably break after a while.
