No, it is not
This boot is a good with with a moderate arch. It has plenty of support. One thing that you can do is buy a custom orthotic or purchase a green or yellow super feet orthotics (those have the highest arch support of the superfeet line) to help customize the boot to your foot profile.
Hello! The Women's US 9.5/EU 42 measured 27 centimeters for Zamberlan's 230 SH Crosser Plus GTX RR boot. Please feel free to contact us with any further questions, have a great day!
Thank you for your inquiry.
Very often customers have reported that Zamberlan footwear is a half size larger than they typically wear. While this boot is built on a medium last it does feature and comfortable wider toe box. The last that is used for this boot offers a good technical fit for the heel and ankle but has a roomy toe box. Customers have also reported the width fitting true to size with some feeling it was on the wider side.
I think if you do not generally buy footwear in the wide width and just need a little more room in the toe box area than this boot should work well for you. Of course if you choose to order this boot and it does not fit for you we always offer our Fit Guarantee so we can help you get the fit you need. Please feel free to contact us with any further question, have a great day!
