I have semi-customized Jackson Elites (my skate fitter had them cut off the top eyelet to give it more of a dance profile, and they're D ball, B heel--I'd never had my feet measured in so much detail before, and it actually explains a lot about my inability to find shoes that fit.) Obviously I've got WIDE feet (well, wide in front) and the customizable width works really well for me. However, I will say, don't skimp on blades. I did, getting the cheapest pair he was willing to sell, and I'm fed up with them after only five months.
My friend just got a new pair of SP Teris for synchro, and is rather fond of them. I didn't try any Riedels, but she has, and she said that the problem she ran into is that the toeboxes tend to run narrow, so if you have wideish feet it might be a problem. The fitter I go to deals mostly in Jacksons and Grafs, so I took his recommendation for what I was willing to spend (I didn't want to go over $450 total for boots and blades.)
