Unfortunately, we do not issue refunds for Sole Warranty credits. These warranties are offered by the manufacturer and we only have the option of issuing a replacement pair or store credit towards another pair of shoes (which does void any further durability guarantees on the pair purchased with credit).
The only time a refund could be considered in this case would be if you needed a new pair faster and purchased the replacement pair early. In this case, we are able to refund the credit retroactively (and would void any potential warranty of the pair of shoes that was purchased early).
I hope you find this helpful.
