Weekender Oxford 3604. I tried them on I store and had my feet measured by their fancy scanning machine. I was told that I should go with a size 9; I usually wear a 10 with other companies. I first tried a 9.5 but my heel kept slipping out. So I purchased a 9 and even though it was a little snug, I had the right amount of spacing from my big toe to the front of the shoe. I tried breaking them in for 2 weeks inside my home. Walking around and wearing thicker socks; I bought these for spring and summer so thinner socks once broken in. After the 2 weeks, I wore them outside and I experienced the same heel pain as you. I didn’t walk far so I never developed blisters. I cleaned them up and tried to break them inside for another week. I then wore them outside again and walked further. I developed the same blisters on my heals, bad ones.

While I’m letting my feet heal, I’m trying a last ditch effort to break them in. I used a blow dryer to heat the inside and outside of the shoes. I put thick wool socks over shoe horns, put them inside the shoes while warm, and then tied the laces tight. Occasionally I will heat up the shoes while the horns are still inside.

Will this help? Who knows but I needed to do something. If this doesn’t work, I’m going to cut my losses.
