This isnt the first pair of Keen Targhee IIs Ive purchased. When I walk I find that I have to crunch up my toes to keep these from falling off, I actually tripped on them the other day. I scavenged a sternum buckle off of a carseat that had been left on the curb, but the way the Yepps straps are constructed meant that I couldnt thread it on. Honestly I wished it were built more Sturdy because I actually liked it. I have wide feet and they were a good fit. My entire life a size 3 has ALWAYS been an EU 36. The originals are the best . I will also say the CAS latency at 16 is really good too. Nice feature is being able to swing down while attached to open tailgate. After 2.
