I have been wearing this brand and model for a few years. Something changed as they now have metal shanks! I work for a major airline and while walking thru security today I "beeped". I sent the shoes thru the Xray and the agent stated there is indeed a METAL SHANK. Bad news for me is I bought them in August and haven't had a chance to wear them until today....outside the return window. Time to look for a new brand of shoe!
