I contacted the Tieks customer service asking if they would recommend going up a size. The service rep suggested that I, instead, try wearing them around the house for a few days with thick socks to stretch them out a bit.
I did as she suggested. They began to feel better and better. After a time, I took them for a stroll to the store on my grocery shopping list. Then as they began to stretch out more, I started wearing them to school while I was teaching.
It has been exactly 1 month but I am very pleased with these shoes. They have, indeed, stretched to fit my wide feet. My favorite thing about them though, is how light they feel. Anyone who knows me well can tell you that I hate heavy shoes. It took SO long to find a pair of sneakers for working out because sneakers are so heavy and I just can't stand the weight on my feet. These Tieks are very light-weight and I love them.
I also really enjoy the light blue sole; the signature Tiek look. It adds a touch of fun and cuteness!
I am considering investing in a second pair (probably the Taupe color since they have it again in my size. When I bought the navy, I really wanted Taupe. But my size was out!) so I can switch them in and out. I am debating waiting a few months though to see how these hold up after wearing them a bunch. I've seen a few reviews who say the sole fell off their Tieks after a month or 2. I'd be very upset if I bought a second pair only to have the sole fall off the first pair after only a month. But those reviews are few and far between. I've seen many more reviews saying their Tieks have lasted years.
