Heelys Inc. rejected a second unsolicited buyout offer from Skechers USA Inc., saying the $142.8 million cash offer is too low. In a statement issued after the market close on Tuesday, the maker of wheeled shoes for children said its board rejected Skechers $5.25 per share bid.

“After careful consideration, our Board rejected the offer after concluding that their proposal was not in the best interest of our stockholders,” chairman Gary Martin said in a statement. “The Board believes the $5.25 offering price does not reflect the value of Heelys and that entering into discussions with Skechers based on their unsolicited proposal is premature at this time.”

Skechers latest bid of $5.25 per share followed an offer made on May 28, when Skechers proposed a purchase price of between $4.75 and $5.10 per share.

Shares of Dallas-based Heelys fell 5 cents to $5.30 in Tuesday trading. Skechers shares fell 96 cents, or 4.9 percent, to $18.56.
