Update: I really can't recommend that people do business with UP. I've tried to support and promote them, but they just can't run the business. Customer service is non-existent, you pay both ways for exchanges, refunds take forever. Sizing between models is all over the place which leads to massive fees for shipping shoes both directions. I finally gave up trying to get something besides UPLace to fit. Probably ate $100 in shipping fees and haven't received a refund weeks after giving up and shipping the last (tiny) pair back. I'm done with UP.
Odd, I have recieved pretty immediate feedback to inquiries with UP. Just sent in 6 pairs of shoes for resole, so I’m hoping my experience stays positive.
