I first visited my local DSW and tried on a pair of Sperry Intrepid in my usual size 6. I found them to run true to size and width for my normal-to-wide feet. They were as comfortable as many had mentioned (hard to tell if they will need to be broken in until I wear them for an extended period of time). The shoe vamp was low and short, so combine that with my narrow heel, my foot was flip-flopping out as I walked. Tightening the laces helped but that means I won't be able to lazily slip my foot in and out with the laces tied.
While I was mulling over the pair I tried on, I suddenly had an ah ha! moment. Why not give the kids' version a try to save some money? I ended up ordering another style in kids, the Sperry Top-Sider Bluefish in size 4 wide US Big Kid (sold here) in two colors: linen/spring plaid (below left) and linen/oat (below right).
The kids' Bluefish came in two widths, regular and wide. I chose the kids' wide based on reviews and they are indeed comparable to the normal width in women's. If you have narrow feet, I'd recommend giving the regular width in kids' a shot.
I wish I had also ordered the Intrepid along with the Bluefish for side-by-side comparisons. Basing solely on memory and feel, the kids' Bluefish did not flip-flop on my feet like the women's Intrepid did, so I'd venture to guess that 1) the shoe vamp on the kids' Bluefish is higher than the women's Intrepid or 2) the women's Intrepid has been stretched out from numerous wears in store. It's entirely possible that the kids' Bluefish will stretch out with time, but it's a risk I'm willing to take. Now I just have to decide which color to keep. Would you vote for oat or spring plaid?
