Size 3.5 for 7 month old walking baby. Pretty cute, but too stiff and my son would not walk in them. Sent them back and got stride rites&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Stride-Rite-SRT-SM-Kade-First-Walker-Infant-Toddler/dp/B004GCJT4G/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Stride Rite SRT SM Kade First Walker (Infant/Toddler)</a>.  My son walked in them right away with many squeels of delight.  My 1st child (xw size) wouldn't walk in anything but stride rites.  I was hoping to save a little money with the 2nd child (m/regular size), but it looks like he loves stride rites too.
