I bought a pair of XF-Accelerators for mt Granddaughter for her Birthday and she just loves them.
Skechers says that the shoes take some getting used to, but she was wearing them from the minute she opened the box with not a single problem. No getting used to, no learning to walk differently, nothing.
Maybe it is because she was a figure skater for 14 years and so is used to having to balance when standing without side support and has good ankle strength from her skating. I don't know but in any case she has been wearing them for about a month now and the only complaint she has about them was that they need to have a wider selection of colors. Not that the colors they have are bad, but she likes some colors they don't currently offer in this particular model of shoe though they do offer the colors she likes in other models but those models don't have the same features she wanted that this model does have. Perhaps when they are out for a longer time Sketchers may widen the selection of colors further.
